When Cu4I4 cubane meets Cu3(pyrazolate)3 triangle: dynamic interplay between two classical luminophores functioning in a reversibly thermochromic coordination polymer

A supramolecular dual emissive system incorporating two classical copper(I)-cluster-based luminophores, namely, Cu4I4 and Cu3Pz3 (Pz = pyrazolate), is reported. The targeted luminescent coordination polymer exhibits reversible thermochromism spanning from green to orange-red.
