Abstract
A cuprous cluster-based luminescent coordination polymer [Cu(OPY)Cl]n (1, OPY = 4,4′-(oxybis (4,1-phenylene))dipyridine) has been hydrothermally synthesized and structurally characterized. Compound 1 consists of bent butterfly dinuclear [Cu2Cl2] core and V-shaped OPY ligand, which exhibits a perpendicularly interpenetrated 2D + 2D → 3D structural characteristic. Compound 1 emits orange red luminescence originated from the dual-emitting behavior at room temperature in the solid state. Its photoluminescence properties have been fully studied and verified by time-dependent density functional theory (TD-DFT) calculations. In addition, the grinding and temperature dependent luminescence properties of 1 have also been investigated in detail.
