Three new Cu(I) CPs, namely, {[Cu₂(DPMF)₃(CN)₂]}_n (1), {[Cu₂(DPMF)₂(CN)₂]·DMSO}_n (2), and {[Cu(DPMF)(CN)]·DMAC·MeOH}_n (3) were synthesized for the first time using an AIE ligand DPMF [DPMF = 4,4′-((9H-fluoren-9-ylidene)methylene)dipyridine]. X-ray structural analysis has revealed that 1 shows a 1D double-chain structure, 2 displays a hexagonal graphene-like 2D layer architecture with 6³-hcb topology and 3 exhibits a 3D framework with 6⁶-dia topology, in which DPMFs are arranged in a windmill-like shape. The differences in their structures are mainly due to the diverse torsions of the DPMF bridges. Furthermore, 3 possesses excellent thermal and solvent stability, and the luminescence measurements indicate that 3 can detect TNP with high sensitivity and selectivity and good recyclability. The emission quenching effect is realized by the energy transfer and electron transfer between 3 and TNP. Moreover, a luminescent test paper is designed to realize the portable detection of TNP in practical applications. These experimental results suggest that 3 can be a potential sensor for TNP.

三种基于AIE配体的Cu（I）配位聚合物：TNP的合成，结构和发光传感

三种新的Cu（I）CP，即{[Cu ₂（DPMF）₃（CN）₂ ]} _n（1），{[Cu ₂（DPMF）₂（CN）₂ ]·DMSO} _n（2），和{[Cu（DPMF）（CN）]·DMAC·MeOH} _n（3）首次使用AIE配体DPMF [DPMF = 4,4'-（（9 H -fluoren-9-ylidene）亚甲基）二吡啶]。X射线结构分析显示1显示1D双链结构，2显示具有6 ^3-的六方石墨烯状2D层结构。HCB拓扑和3个表现出与6三维框架⁶ -直径的拓扑结构，在其中DPMFs布置在风车状。它们结构的差异主要是由于DPMF桥的扭转不同所致。此外，3具有出色的热稳定性和溶剂稳定性，并且发光测量结果表明3可以检测TNP，具有高灵敏度和选择性以及良好的可回收性。发射猝灭效应是通过3和TNP之间的能量转移和电子转移实现的。此外，设计了一种发光试纸以在实际应用中实现便携式检测TNP。这些实验结果表明3可以是TNP的电位传感器。
