丁二炔类材料(diacetylenes)由于其独特的聚合方式(即拓扑化学聚合,topochemical polymerization)以及聚合后形成的共轭高分子材料表现出优异的电学、非线性光学等特性,很早就受到了人们的广泛关注.当然,不是所有的丁二炔类化合物都能发生晶体内的拓扑化学聚合反应,这需要丁二炔单体分子在固态下首先要满足一定的分子堆积结构,同时还需要有合适的外界条件,譬如加热、光照、?射线辐射等条件来刺激该反应的发生.本文从分子结构的设计合成和超分子化学结构的构建两个角度出发,系统总结了能够实现丁二炔类材料发生晶体内拓扑化学聚合的各种策略,讨论了相关丁二炔类化合物的反应特性及反应后的分子结构特征,最后简要介绍了聚丁二炔类共轭高分子材料在光、电、传感等领域的潜在应用.通过本文对丁二炔类材料拓扑化学聚合行为研究的系统总结,希望能够再次激起化学工作者对于利用拓扑化学聚合反应来制备共轭高分子材料的研究兴趣,从化学合成的角度进一步发展一些新的可发生拓扑化学聚合反应的单体分子结构单元,丰富该类材料体系,促进相关研究的发展.
Diacetylenes have long been subjected to excellent electrical and non-linear optical properties due to their unique polymerization methods (topochemical polymerization) and the conjugated polymer materials formed after polymerization Of course, not all diacetylene compounds can undergo intracrystalline topological chemical polymerization reaction, which requires diacetylene monomer molecules in the solid state must first meet certain molecular packing structure, but also need to have Appropriate external conditions, such as heating, light, radiation and other conditions to stimulate the reaction conditions.In this paper, from the molecular structure of the design and synthesis of supramolecular chemical structure of the two aspects of the establishment of a systematic summary of the diacetylene The various tactics of intracrystal topological chemical polymerization were discussed. The reaction characteristics of the related diacetylene compounds and the molecular structure characteristics of the reaction were discussed. At last, the polybutadiene acetylene conjugated polymers were briefly introduced in the fields of light, electricity, Sensing and other fields of potential applications.Through this article on the diacetylene topological chemical polymerization behavior of the systematic summary of the hope that Once again, arousing the interest of chemists in the research of topological chemical polymerization for the preparation of conjugated polymers, the further development of some new molecular structural units that can undergo topological chemical polymerization from the viewpoint of chemical synthesis and enrichment of such materials System to promote the development of related research.
