摘要

本文合成了三种具有不同π -π共轭和配位数的共价有机聚合物（cop）。作为发光探针，COP-H3对含oh的硝基炸药具有较高的选择性，而COP-H2对三硝基苯酚和2,6- dnp具有较高的选择性。它们的感应行为可以用吸收竞争猝灭机制来解释。

1,2,3,4,5,6-Hexakis(4-bromophenyl)benzene-based covalent organic polymers as specific luminescent probes for the selective sensing of nitro-explosives†

Here, we synthesized three covalent organic polymers (COPs) with varying π–π conjugation and coordination numbers. COP-H3, as a luminesent probe, exhibited a highly selective sensing of OH-containing nitro-explosives, while COP-H2 exhibited high selectivity for trinitrophenol and 2,6-DNP. Their sensing behavior could be well explained by the absorption competition quenching mechanism.
