As one of the most potential platforms for heterogeneous catalysis, two-dimensional porphyrin-based covalent organic frameworks (COFs) have attracted great research interests. In this work, following the correlation of COF structure and their performance, a type of donor–acceptor 2D COF (Por-COF-Zn) based on porphyrin and thiophene units was designed and easily constructed by one-pot method using 5
作为最具潜力的非相催化平台之一,二维卟啉基共价有机框架 (COFs) 引起了极大的研究兴趣。在这项工作中,遵循 COF 结构及其性能的相关性,设计了一种基于卟啉和噻吩单元的供体-受体 2D COF (Por-COF-Zn),并使用 5,10,15,20-四-(4-氨基苯基)卟啉 (TAPP)、噻吩并[3,2-b]噻吩-2,5-二甲醛和乙酸锌采用一罐法轻松构建。合成的 COF 材料经测试显示出高结晶度以及良好的热稳定性和化学稳定性。Brunauer-Emmett-Teller (BET) 测量结果表明,Por-COF-Zn 的比表面积为 413.6 m2 g-1,孔体积为 0.279 cm3 g-1。瞬态光电流响应和 EIS 测量还表明,Por-COF-Zn 表现出光生电子/空穴对的有效分离。通过使用 N-苯基-邻苯二胺和苯甲醛的分子内环化形成苯并咪唑衍生物,进一步评价所得 COF 的光催化
