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.
