A series of substituted 1,4-benzenediboronic acids (BDBA) was synthesized and their thermal properties investigated. Two diboronic acids were studied as building-blocks for covalent organic framework (COF) formation, namely 2,5-dimethoxy-1,4-benzenediboronic acid and 2-nitro-1,4-benzeneboronic acid. Interestingly, substitution of the BDBA core caused a dramatic decrease of the polymerization temperature leading to the formation of a less organized structure.
一系列取代的1,4-苯二硼酸(BDBA)被合成,并研究了它们的热性质。选择两种二硼酸作为共价有机骨架(COF)形成的构建块,即2,5-二甲氧基-1,4-苯二硼酸和2-硝基-1,4-苯硼酸。有趣的是,BDBA核心的取代导致了聚合温度的显著降低,从而形成了较为无序的结构。
