本文合成了一种含有两种不同Ag+配位模式的发光三维配位聚合物[Cd II（pmd）{AgI（CN）2}2]（1; pmd =嘧啶）（CP）。1表现出热致变色发光，伴随着正的热伸长的Ag <$Ag距离。此外，在先前报道的磷光Ag基CP或金属有机框架中，1显示出明亮的磷光，具有最高的光致发光量子产率（Φem），在室温下约为60%。
A luminescent three-dimensional coordination polymer (CP) of [CdII(pmd){AgI(CN)2}2] (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 (Φem), approximately 60% at room temperature, among previously reported phosphorescent Ag-based CPs or metal–organic frameworks.
