A 1D coordination polymer (CP), (TBA) [Bi(bp4do)Br₄] (1), was synthesized by the assembly of 4, 4' - bipyridine -N, N'-dioxide (bp4do) and Bi³⁺ (TBA⁺=tetrabutylammonium). 1 exhibits a red luminescence with a quantum yield of up to 69%. A solid-state thin-film sensor (1/PVP) with extremely high luminescence stability was prepared by combining 1 with polyvinyl pyrrolidone (PVP). 1/PVP has a wide - range sensing capability for 11 NH₃/amine vapors with rapid response. During the sensing process, its luminescence color changed from red to blue, which was easy for naked -eye observation. The sensing mechanism is NH₃/amine-induced collapse of the framework of 1. Furthermore, 1/PVP has been successfully applied to monitoring food freshness such as meat/aquatic products.

以二甲基亚砜(DMSO)为溶剂，通过溶剂热挥发法合成了硫酸锌开放骨架[Zn(SO₄)(DMSO)] (1)基质。再将2，6-萘二酸(P)低剂量掺杂到基质1中，制备了一种同时具有荧光和室温磷光(RTP)性质的复合物P@1。P@1具有肉眼可见的绿色RTP，持续时间约为2 s。P@1对Pb²⁺表现出选择性磷光增强响应，检测限为2.52 μmol·L^-1。其检测机制主要是Pb—O配位作用诱导体系磷光增强。有趣的是，P@1可作为双通道探针通过荧光猝灭快速检测Fe³⁺，检测限为0.038 μmol·L^-1。其识别机制可能归因于P@1与Fe³⁺之间的竞争性能量吸收。
