Throughout human history, economic activity and resource consumption have been strongly linked, with increasingly immediate consequences for our planet and climate. Navigating our way to a future in which environmental impacts can be decoupled from the amenities of modern living is arguably the critical challenge of our time. This program seeks to address this by connecting ligand design, coordination chemistry and materials science, viewed through a lens of sustainability. The long-term goal is to develop new molecular materials and synthetic methodologies that can (a) efficiently harvest and interconvert light and electrical energy; and (b) employ sustainable feedstocks in the production of value-added materials. The scientific approach that will be taken to achieve these goals is to design molecular scaffolds (ligands) that can be used to control the electronic properties and reactivity of transition metal coordination complexes. The properties that make these ligands useful in one context, such as endowing control over electronic excited states, can engender productive chemistry in another: for example, imparting chemical control in synthesis through stabilizing reactive intermediates. Thus, by diving deep into ligand design, this approach promises impact in a range of areas, from the construction of abundant metal-based light absorbers for sustainable solar energy harvesting, to the discovery of new energy-efficient emitters for display technologies, to the development of low-waste catalytic routes to value-added chemicals using sustainable feedstocks. By combining fundamental molecular structure-property/reactivity studies with a pursuit of practical applications, the proposed research program promises both the potential of significant and immediate impact, and to add new understanding to the chemist's toolbox. Trainees participating in this research program will emerge uniquely skilled, equipped with an industrially relevant knowledge base in synthetic inorganic and organometallic chemistry; ligand design, coordination chemistry and catalysis; and advanced characterization, augmented by knowledge gained through collaboration with leading researchers around the world in highly specialized spectroscopic techniques. Through engaging in both cutting-edge research and meaningful outreach, program participants will develop a sense of creativity and societal context that should be highly desirable to Canada's rapidly growing green energy and renewable resource sectors.

纵观人类历史，经济活动和资源消耗一直密切相关，对我们的星球和气候产生越来越直接的影响。走向一个环境影响与现代生活便利设施脱钩的未来，可以说是我们这个时代面临的严峻挑战。该项目旨在通过可持续性的视角，将配体设计、配位化学和材料科学联系起来来解决这个问题。长期目标是开发新的分子材料和合成方法，这些材料和合成方法可以（a）有效地收集和相互转换光能和电能； (b) 在生产增值材料时采用可持续原料。实现这些目标的科学方法是设计可用于控制过渡金属配位络合物的电子特性和反应性的分子支架（配体）。使这些配体在一种情况下有用的特性，例如赋予对电子激发态的控制，可以在另一种情况下产生富有成效的化学：例如，通过稳定反应中间体在合成中赋予化学控制。因此，通过深入研究配体设计，这种方法有望在一系列领域产生影响，从构建用于可持续太阳能收集的丰富的金属基光吸收器，到发现用于显示技术的新型节能发射器，再到开发利用可持续原料生产增值化学品的低废物催化路线。通过将基本的分子结构-性质/反应性研究与对实际应用的追求相结合，拟议的研究计划有望产生重大和直接的影响，并为化学家的工具箱增添新的理解。参加该研究项目的学员将拥有独特的技能，并具备合成无机和有机金属化学方面的工业相关知识库；配体设计、配位化学和催化；和先进的表征，并通过与世界各地高度专业化光谱技术的领先研究人员合作获得的知识进行增强。通过参与前沿研究和有意义的推广，项目参与者将培养创造力和社会背景，这对于加拿大快速增长的绿色能源和可再生资源行业来说是非常理想的。
