摘要

通过4,4'-氧化联吡啶(bp4do)与Bi3+的组装合成了具有一维链结构的配位聚合物(CP):(TBA)[Bi(bp4do)Br4](1),其中TBA+=tetrabutylammonium.1具有红色发光,量子产率高达69％.通过将1与聚乙烯吡咯烷酮(PVP)复合,制备了一种具有极高发光稳定性的固态薄膜传感器(1/PVP).1/PVP具有对11种NH3/胺蒸气的广谱传感能力,且响应迅速.在传感过程中其发光颜色由红色变为蓝色,易于裸眼观测.其检测机制是NH3/胺诱导1的骨架的坍塌.此外,该固态薄膜传感器已成功应用于肉类/水产品等食品新鲜度的监测.

Abstract

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 quan-tum yield of up to 69％.A solid-state thin-film sensor(1/PVP)with extremely high luminescence stability was pre-pared 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.CCDC:2348704.
