Metal-containing polymers (metallopolymers) are a class of materials in which metal centres can introduce properties and functions that complement state-of-the-art organic macromolecules. This proposal details a novel, yet simple, synthetic strategy towards of a new class of functional, conjugated metallopolymers via polymerisation routes based on olefin metathesis. The proposed research involves study of viable cyclic metal-containing molecules for polymerisation, mechanistic understanding of the polymerisation process, and analysis of the structure-function relationship in the polymeric materials. This strategy will significantly improve the synthetic scope towards main-chain metallopolymers, enabling the generation of a diverse library of processable materials in which the electronic structure can be altered in a modular fashion by simple synthetic modifications, enabling band gap tuning to access insulating, semiconducting and conducting materials. The incorporation of metals into conjugated polymer chains is of great interest due to enhancement of spin-orbit coupling, facilitating an increase in triplet excited state population for use in both light-emitting diodes and photovoltaic technologies. Additional applications include electrocatalysis, stimuli-responsive and sensing materials, and patternable precursors to magnetic materials.

含金属的聚合物（金属聚合物）是一类材料，金属中心可以在其中引入与最先进的有机大分子相辅相成的特性和功能。该建议详细介绍了一种新型但简单的合成策略，用于通过基于烯烃元理解的聚合途径来对新的功能，共轭金属聚合物的新型策略。拟议的研究涉及研究可行的循环金属分子，以进行聚合，对聚合过程的机械理解以及对聚合物材料中结构功能关系的分析。该策略将显着改善对主链金属聚合物的合成范围，从而能够生成各种可加工材料库，其中可以通过简单的合成修改以模块化的方式改变电子结构，从而使带隙调整能够访问绝缘，半导体和指导材料。由于自旋轨道耦合的增强，将金属掺入共轭聚合物链中引起了人们的极大兴趣，从而促进了在发光二极管和光伏技术中使用的三胞胎激发态种群的增加。其他应用包括电催化，刺激响应和传感材料以及对磁性材料的图案前体。
