Abstract

A luminescent three-dimensional coordination polymer (CP) of [Cd^II(pmd){Ag^I(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 (Φ_em), approximately 60% at room temperature, among previously reported phosphorescent Ag-based CPs or metal-organic frameworks.
