A new series of TPATTh-based CMPs have been synthesized via a readily synthetic scheme of C–H direct arylation polymerization (DAP) that involves thiophene-flanked arenes, tris[4-(2-thienyl)phenyl]amine (TPATTh) and commercially available multi-brominated aryls, (2,2′,7,7′-tetrabromo-9,9′-spirobifluorene (TBrSBF), 1,3,6,8-tetrabromopyrene (TBrPy), 2,5-dibromopyrazine (DBrPy), and 1,6-dibromopyrene(DBrPz)). Preactivation of the C–H bonds in the aromatic monomers is not required. The resulting TPATTh-based CMPs display good thermal stability. The porosities of the TPATTh-based CMPs are lain on the structures of the multi-brominated aryls. The TPATTh-based CMPs present good fluorescence emission performances either in the solid states or dispersed in the solvents, and show different colors under 365 ​nm fluorescence irradiation. The resulting TPATTh-based CMPs were used to fluorescence sense to I2, PA, DNP, and o-NP with high Stern-Volmer quenching constants (Ksv).

三[4-(2-噻吩基)苯基]胺基共轭微孔聚合物通过直接芳基化聚合合成荧光敏感碘和硝基苯酚

通过 C-H 直接芳基化聚合 (DAP) 的简易合成方案合成了一系列新的基于 TPATTh 的 CMP,该方案涉及噻吩侧翼芳烃、三 [4-(2-噻吩基)苯基] 胺 (TPATTh) 和商业化可用的多溴芳基化合物,(2,2',7,7'-tetrabromo-9,9'-spirobifluorene (TBrSBF)、1,3,6,8-四溴芘 (TBrPy)、2,5-二溴吡嗪 (DBrPy) , 和 1,6-二溴芘 (DBrPz))。不需要预先激活芳香族单体中的 C-H 键。由此产生的基于 TPATTh 的 CMP 显示出良好的热稳定性。基于 TPATTh 的 CMP 的孔隙率位于多溴芳基的结构上。基于 TPATTh 的 CMP 在固态或分散在溶剂中均表现出良好的荧光发射性能,并在 365 nm 荧光照射下显示出不同的颜色。生成的 TPATTh-基于 CMP 的荧光检测具有高 Stern-Volmer 淬灭常数 (Ksv) 的 I 2、PA、DNP 和 o-NP。
