酞菁及其金属螯合物,具有很高的热稳定性,且具有大π键共轭体系,是重要的有机半导体和光导体之一。许多作者认为,合成聚酞菁类化合物是制备具有高电导率的耐高温高分子材料最有希望的方向之一。导电性聚酰亚胺具有优良的耐高温及耐辐射性能,目前正在开发之中。最近,Shirai等将金属-酞菁环引入到聚酰亚胺的主键中,合成了具有一定导电性能的、在主链中含金属-酞菁环的酮酐型聚酰亚胺。本文以3,3’、4,4’-二苯醚四甲酸二酐、邻苯二甲酸酐、尿素、无水氯化铜以及五种二元胺为主要原料,在shirai等工作的基础上,引入了有柔顺性的醚键,首次合成了五种在主链中含有酞菁铜环的双醚酐型聚酰亚胺。这些聚合物具有很高的热稳定性,也具有半导性能。本文对这些聚合物的导电性能、分子结构和超分子结构之间的关系,作了初步探讨。
Phthalocyanine and its metal chelate, with high thermal stability, and has a large π-conjugated system, is one of the important organic semiconductors and photoconductors. Many authors believe that the synthesis of polyphthalocyanine compounds is one of the most promising directions for the preparation of high-temperature high-temperature polymer materials with high conductivity. Conductive polyimide has excellent high temperature and radiation resistance, which is currently under development. Recently, Shirai et al. Introduced a metal-phthalocyanine ring into the main bond of polyimide to synthesize an anhydride-type polyimide containing a metal-phthalocyanine ring having a certain conductivity in the main chain. In this paper, 3,3 ’, 4,4’-diphenyl ether tetracarboxylic dianhydride, phthalic anhydride, urea, anhydrous copper chloride and five diamines as the main raw material, based on the work of shirai , The introduction of a flexible ether bond, the first synthesis of five in the main chain containing copper phthalocyanine bis ether anhydride type polyimide. These polymers have high thermal stability and also have semiconducting properties. In this paper, the conductivity of these polymers, molecular structure and the relationship between supramolecular structure, made a preliminary study.
