Polymers comprised of transition metals and stable organic radicals are two classes of multifunctional materials that have shown significant promise based on their desirable redox, magnetic, conductive, stimuli responsive, and pre-ceramic properties. However, the scope of the current state of the art methods used to prepare these polymers is limited with respect to the transition metals and stable radicals that can be incorporated. The goals of the proposed research program involve the development and exploitation of synthetic methodologies allowing for the realization of multifunctional polymers incorporating a range of transition metals and stable organic radicals as part of three different projects. 1) We will develop transition metal-catalyzed and controlled radical polymerization protocols for the synthesis of highly metallized metal-containing polymers (MCPs) based on first row transition metals. We will then explore the pyrolysis of MCPs to potentially produce nanoparticles that may catalyze the oxidation of water, a key reaction in the storage of solar energy. 2) We will develop synthetic methods for the realization of p-type pi-conjugated MCPs and utilize the properties of the incorporated transition metals to tune the energy of their highest occupied molecular orbitals (HOMOs), their electromagnetic radiation absorption profiles, and the self-assembly properties of the polymers. Each of these variables may play an important role in increasing the efficiency of bulk heterojunction solar cells. 3) We will explore routes allowing for the isolation of novel families of radical-containing polymers, and explore their electrochemical properties and potential utility as hole transport materials for dye regeneration in dye-sensitized solar cells. The proposed research program is highly innovative and will make significant contributions to Canadian excellence through the development (and potential commercialization) of novel technologies and partnerships with Canadian industry. It will also allow 29 highly qualified personnel (HQP) to be trained during the 5 year funding period.

由过渡金属和稳定的有机自由基组成的聚合物是两类的多功能材料，它们基于其所需的氧化还原，磁性，导电，刺激响应和前陶瓷特性显示出显着的希望。 但是，对于可以掺入的过渡金属和稳定的自由基，用于制备这些聚合物的最新方法的当前状态范围受到限制。 拟议的研究计划的目标涉及对合成方法的开发和开发，允许实现多功能聚合物，这些聚合物融合了一系列过渡金属和稳定的有机自由基作为三个不同项目的一部分。 1）我们将基于第一行过渡金属制定过渡金属催化和受控的自由基聚合方案，以合成高度金属化的金属聚合物（MCP）。 然后，我们将探索MCP的热解，以产生可能催化水的氧化的纳米颗粒，这是太阳能储存的关键反应。 2）我们将开发用于实现P型PI偶联的MCP的合成方法，并利用掺入过渡金属的特性来调整其最高占用的分子轨道（HOMOS）的能量，其电磁辐射吸收轮廓以及Polymers的自我组装特性。 这些变量中的每一个都可能在提高批量异质结太阳能电池的效率方面起重要作用。 3）我们将探索允许隔离含有自由基的聚合物家族的途径，并探索它们的电化学特性和潜在的效用，作为染料敏化太阳能电池中染料再生的孔传输材料。 拟议的研究计划具有很高的创新性，并通过与加拿大工业的新技术和合作伙伴关系的开发（以及潜在的商业化）为加拿大卓越做出了重大贡献。它还将允许在5年资金期间培训29名高素质的人员（HQP）。
