Ozin, G.A., Lohr, J., Energy Materials Discovery for a Sustainable Future, Royal Society of Chemistry, 2021.
– Energy consumption is one of the biggest challenges of the 21st century. How will billions of humans survive on Earth in the future?
The demand for energy will soon exhaust traditional resources such as oil, gas and coal. Developing cost effective ways of using renewable sources such as solar energy is important for future generations.
This book will enable you to explore the vital role that new materials play in ensuring life on Earth is sustainable. You’ll learn about inexpensive energy generation and storage and gain a greater understanding of the energy crisis the world is facing.
Ozin, G.A., Ghoussoub, M, The Story of CO2 – Big Ideas for a Small Molecule, University of Toronto Press, 2020
– The climate crisis requires that we drastically reduce carbon dioxide emissions across all sectors of society. The Story of CO2 contributes to this vital conversation by highlighting the cutting-edge science and emerging technologies – a number of which are already commercially available – that can transform carbon dioxide into a myriad of products such as feedstock chemicals, polymers, pharmaceuticals, and fuels. This approach allows us to reconsider CO2 as a resource, and to add “carbon capture and use” to our other tools in the fight against catastrophic climate change.
The Story of CO2 explores all aspects of carbon dioxide, from the atomic to the universal perspective, and takes the reader on an epic journey into our physical world, starting from the moment of the Big Bang, all the way to the present world in which atmospheric CO2 concentrations continue to grow. This story seeks to inspire readers with the latest carbon utilization technologies and explain how they fit within the broader context of carbon mitigation strategies in the shift towards a sustainable energy economy.

Ozin, G.A., Arseneault, A., Nanochemistry: A Chemistry Approach to Nanomaterials, Royal Society of Chemistry, First Edition November 2005, Second Edition 2009.
– As of this writing, this is the “first teaching textbook on the subject of Nanochemistry”. It has been written by chemists in an attempt to fill the nano-chemistry teaching void. The content of the book has been carefully selected and organized to teach the basic principles of Nanoscience through the subject of Nanochemistry. Because of the interdisciplinary and comprehensive approach adopted by the authors, the book should be useful to a broad audience at levels that encompass the needs of the specialist as well as the lay reader.
Ozin, G.A., Cademartiri, L., Nanochemistry: Principles and Practice, Wiley-VCH 2009.
– This text book is ideal for interdisciplinary courses – bridging chemistry, materials science, physics and biology. Adopting a completely new and visionary approach, this is a unique learning tool, focusing on just six concepts crucial for understanding nanochemistry: surface, size, shape, self-assembly, defects and the interface of biology and nanochemistry. These concepts are elucidated through the analysis of six materials representing the real life application of the nanochemistry concepts. The teaching questions included provide real “food for thought”, thus training students to think as a researcher does and so develop problem solving skills.

– Breakthrough paper that describes a synthetic route to ultrathin inorganic nanowires with thicknesses below 2 nm, a size right at the threshold where molecules meet nanostructures in one-dimension. Specifically, the use of amine chemical crosslinking of ultrathin inorganic nanowires as a bottom-up strategy for nanostructure fabrication as well as a chemical detection platform is demonstrated. Nanowire microfibers are produced by chemospinning nanowire dispersion into an amine crosslinker solution at room temperature. Nanomembranes with thicknesses down to 50 nm were obtained by injecting the nanowire dispersion at the amine crosslinker-solution/air interface. Furthermore, the sensitivity of the nanowire to amine crosslinkers allowed development of a novel sensing platform for small molecules, like the neurotransmitter serotonin, with detection limits in the picomolar regime.

–Pioneering work that demonstrates enhancement in the photoconductivity of a thin semiconductor film can be achieved by depositing a photonic crystal (PC) onto its backside. The greatest photoconductivity enhancement is observed when the thickness of the film is such that a resonant mode appears within the stop-gap of the PC. Notably, the semiconductor film itself does not need to be periodically structured to exhibit enhanced photoconductivity, allowing the simple architecture of the film-PC construct to be readily applied to a variety of devices including resonant cavity enhanced photodiodes and more efficient photovoltaics.
Mirkovic, T., Foo, M.L., Arsenault, A.C., Fournier-Bidoz, S., Zacharia, N.S., Ozin, G.A., 2007, Hinged Nanorods – A Chemical Approach to Flexible Nanostructures, Nature Nanotechnology 2, 565-569.
– The fabrication of multifunctional nanomaterials and their subsequent utilization for novel applications in various branches of nanotechnology has been intensifying. Particularly in the area of nanomechanics, the design of multicomponent nanostructures with integrated multi-functionality, would enable the construction of building blocks for nanoscale analogues of macroscopic objects. In this paper we introduce a new class of flexible nanostructures – metallic nanorods with polyelectrolyte hinges, which were synthesized by layer-by-layer electrostatic self-assembly of oppositely charged polyelectrolytes on barcode metal nanorods followed by segment selective chemical etching. Nanorods with hinges that consist of one polyelectrolyte bilayer display a considerable flexibility, but with an increased number of bilayers, the flexibility of the hinge is significantly reduced. Magnetically induced bending about the polymer hinge is illustrated through the incorporation of nickel segments into the barcodes and application of an external fluctuating magnetic field.
Puzzo, D., Arsenault, A.C., Manners, I., Ozin, G.A., 2007, Full Color Photonic Crystal Display, Nature Photonics 1, 468-472.
– In our information rich world, it is becoming increasingly important to develop new technologies capable of displaying dynamic and changeable data, for reasons ranging from value-added advertising to environmental sustainability. There is an intense drive at the moment towards “paper-like” displays, devices having a high reflectivity and contrast to provide viewability in a variety of environments, particularly in sunlight where emissive or backlit devices perform very poorly. The list of possible technologies is extensive, including electrophoretic, cholesteric liquid crystalline, electrochromic, electrodewetting, interferometric and more. Despite tremendous advances, the key drawback of all these existing display options relates to color: As soon as an RGB color filter or spatially modulated color scheme is implemented, substantial light losses are inevitable even if the intrinsic reflectivity of the material is very good. In this work, we describe a reflective flat-panel display technology based on the electrical actuation of photonic crystals. These materials display non-bleachable structural color, reflecting narrow bands of wavelengths tuned throughout the entire visible spectrum by expansion and contraction of the photonic crystal lattice. The material is inherently bright in high light environments, has electrical bi-stability, low operational voltage, can be integrated onto flexible substrates, and is unique amongst all display technologies in that a continuous range of colors can be accessed without the need for color filters or optical elements.
Chen, J., von Freymann, G., Choi, S., Kitaev, V., Ozin, G.A. 2006, Amplified Photochemistry with Slow Photons, Adv. Mater., 18, 1915-19.
– Seminal paper that demonstrates for the first time that the photo-activity of TiO2, when chemically fashioned as an inverse opal, can be dramatically enhanced by utilizing slow photons with energies close to the electronic band gap of the semiconductor. By optimizing the energy of the photonic stop gap with respect to the semiconductor electronic band gap, slow photons are effectively harvested in the dielectric part of the material, while suppressing unwanted reflectivity losses. The system is extremely tolerant to structural defects in the photonic lattice, which bodes well for their practical utility in real world applications. In a larger context, the ability to optically amplify photochemistry, by molding photoactive materials and composites in the form of photonic crystals is a universal paradigm that could profoundly advance diverse fields of science.

–Trendsetting paper that describes the development of large-area films of porous elastomeric photonic crystals (EPCs) that can be compressively-decompressively cycled, to reversibly shift the position of the photonic band structure over a large wavelength range. These porous EPC’s, with their low compressive threshold, have been used as imaging materials for obtaining high-accuracy, pressure- and time-dependent colour fingerprints. Further, the pores in EPC’s have been used as hosts for luminescent PbS quantum dots, in order to compressively shift the photonic stop-gap through the near-IR photoluminescence (PL) peak enabling a tunable modification of photophysical characteristics, including suppression and enhancement in emission and dynamic modification of luminescence lifetimes.
Kamp, U., Kitaev, V., von Freymann, G., Mabury, S., Ozin, G.A., 2005, Colloidal Crystal Capillary Columns: Towards an Optical Chromatography, Adv. Mater. 438-453.
–First demonstration that very high structural quality colloidal crystal capillary columns can be produced by a pressure assisted microsphere assembly – these columns display excellent optical quality in the visible and near infrared spectral wavelength range that is invariant to rotation and translation over considerable length scales – such capillary monoliths and their inverse constructs may function as a next generation chromatography stationary phase and enable a novel form of photonic crystal-based optical chromatography.
Landskron, K., Ozin, G.A. 2004, Periodic Mesoporous Dendrisilicas (PMDs), Science 306, 1529-1523,
– Integration of two of the most important classes of nanoscale materials, namely dendrimers and periodic mesoporous silicas, to create an entirely new class of nanocomposite materials. In this work the synthesis of “periodic mesoporous dendrisilicas” is described that consist of dendrimer building blocks having variable cores and generations with end-functionalization by siloxy groups, fashioned into a hierarchical structure with well-defined channel walls and ordered mesoporous channels. The synthesis is based upon the co-assembly of carbosilane dendrimer building blocks with a templating triblock copolymer mesophase. PMDs are expected to find utility as a new generation of controlled chemical and pharmaceutical storage and release materials.

Wong, S., Kitaev, V, Ozin, G.A., 2003, Colloidal Crystal Film: Advances in Universality and Perfection, J. Amer. Chem. Soc., 125, 15589-15598.
– This work paved the way for other researchers to reliably prepare high-quality colloidal crystal films for various applications in diverse research areas. The paper demonstrated major advances in preparation of colloidal crystal films in two important directions: quality of microspheres, where monodispersity was improved to below 2%, and development of reliable universal procedure for preparation of high-quality films using arbitrary sizes of colloidal particles. Importantly, the developed procedure is really facile and versatile, since it uses only simple laboratory equipment, so it can be readily implemented in different research laboratories. Furthermore, the developed procedure features all the necessary elements to be relatively easily-industrially-scaleable.

M. 2000, Self-Assembly of a Silicon Photonic Bandgap Material with a Complete Three-Dimensional Gap at 1.5 Microns, Nature 405, 437-440 (ISI top 20 Photonics).
–Synthesis of the world’s first silicon-based inverse-opal material with a complete photonic band gap centered at a wavelength of 1.5 microns. This was previously considered unattainable, or impossible, by many leading research groups around the world – its reduction to practice is now recognized as a monumental achievement by the international scientific community. By combining detailed theoretical design and innovative materials chemistry, this breakthrough has opened the door to efficient, accurate, and large scale synthesis of not only the silicon inverse opal material, but also a variety of other novel photonic band gap (PBG) architectures, capable of micro-molding the flow of light at 1.5 microns, the wavelength of choice for telecommunications. This has important applications in the fundamental understanding of light-matter interactions and in the use of light signals for processing information.
