A luminescent three-dimensional coordination polymer (CP) of [Cd(pmd){Ag(CN)}] (1; pmd = pyrimidine) comprising two different coordination modes of Ag ions was synthesised herein. 1 exhibited thermochromic luminescence, accompanied by positive thermal elongation of the Ag⋯Ag distance. Moreover, 1 showed a bright phosphorescence with the highest photoluminescence quantum yield (), approximately 60% at room temperature, among previously reported phosphorescent Ag-based CPs or metal-organic frameworks.
本文合成了一种[Cd(pmd){Ag(CN)}]（1；pmd =嘧啶）的发光三维配位聚合物（CP），其中银离子具有两种不同的配位模式。1表现出热致变色发光，同时伴随着Ag⋯Ag距离的正向热伸长。此外，在先前报道的基于银的磷光CP或金属有机框架中，1在室温下具有明亮的磷光，其光致发光量子产率（）最高，约为60%。
