| 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 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. |
