Conjugated microporous polymers (CMPs) with strong fluorescence are great candidates for optoelectronic applications such as photocatalysis and chemical sensing. A series of novel fluorene‐based conjugated microporous polymers (FCMPs) with different electronic structures are prepared by Yamamoto coupling reactions using rationally designed monomers. The FCMPs show a high degree of microporosity, decent specific surface areas, and variable fluorescence. FCMP3, which possesses a triazine knot in the network, exhibits the highest specific surface area of 489 m2 g−1, the largest pore volume of 0.30 cm3 g−1, and the highest solid‐state photoluminescence quantum yield of 11.46%. Chemical sensing performance of FCMPs is studied using a range of nitroaromatic compounds as the analytes. Among the FCMPs, FCMP3 exhibits the highest Stern–Volmer constants of 2541, 4708, and 5241 m−1 for the detection of nitrobenzene, 4‐nitrotoluene, 2,4‐dinitrotoluene, respectively, which are comparable to the detecting efficiency of the state‐of‐the‐art CMP‐based sensing agents.

芴基共轭微孔聚合物:制备和化学传感应用

具有强荧光的共轭微孔聚合物(CMP)是光电应用(例如光催化和化学传感)的绝佳候选者。通过使用合理设计的单体的Yamamoto偶联反应制备了一系列具有不同电子结构的新型芴基共轭微孔聚合物(FCMP)。FCMP显示出高度的微孔性,适度的比表面积和可变的荧光。在网络中具有三嗪结的FCMP3的最高比表面积为489 m 2 g -1,最大孔体积为0.30 cm 3 g -1,并且最高的固态光致发光量子产率为11.46%。使用一系列硝基芳族化合物作为分析物研究了FCMP的化学传感性能。在FCMP中,对于CMP的硝基苯,4-硝基甲苯,2,4-二硝基甲苯的检测,FCMP3的Stern-Volmer常数最高,分别为2541、4708和5241 m -1,与该状态的检测效率相当。最先进的基于CMP的传感代理。
