Abstract

Main-chain metallopolymers are synthesized by olefin metathesis polymerizations. These polymers are mainly produced through acyclic diene metathesis (ADMET) polymerization and ring-opening metathesis polymerization (ROMP). The special metal moieties, metal-binding motifs, and unsaturated macromolecular backbone endow the metallopolymers with unique properties. This review highlights recent advances in studies on the family of main-chain metallopolymers carrying both main-group and transition metals by olefin metathesis polymerizations. We emphasize the synthesis, physiochemical properties, and applications of these polymers. Synthetic strategies are discussed from a perspective of the structure-activity relationship between monomers and polymerization efficiency. The correlations between macromolecular compositions/sequences and emerging properties are highlighted in terms of stimuli-responsiveness, conductivity, and crystalline characteristics. Lastly, we describe the current status of the field and highlight gray areas for future research.

摘要

主链金属聚合物是通过烯烃复分解聚合反应合成的。这些聚合物主要通过无环二烯复分解（ADMET）聚合和开环复分解聚合（ROMP）制备。特殊的金属部分，金属结合基序和不饱和大分子骨架赋予金属聚合物独特的性能。这篇综述着重介绍了通过烯烃复分解聚合同时携带主族金属和过渡金属的主链金属聚合物家族的最新研究进展。我们强调这些聚合物的合成，理化性质和应用。从单体之间的构效关系与聚合效率的角度讨论了合成策略。大分子组成/序列与新兴特性之间的相关性在刺激响应性，电导率和结晶特性方面得到了强调。最后，我们描述了该领域的当前状况，并突出显示了灰色区域，以供将来研究。
