A photoactive copper iodide phosphine-based coordination polymer

Résumé

A coordination polymer based on the polymetallic [Cu4I4] center was synthesized by coordination with a phenyl-based-diphosphine ligand. The structure of this solid formulated [Cu4I4(Ph2P(C6H4)2PPh2)2]n, although crystalline, could not be completely resolved by powder X Ray diffraction. Nevertheless, combining different characterization techniques and in particular the 63 Cu and 31 P solid-state NMR analyses, permit to get insights into the polymeric structure. This coordination polymer appears to be of high dimensionally with possible interpenetrated networks, resulting in low porosity. Photoluminescence characterization revealed original luminescence thermochromic properties ascribed to the photoactive [Cu4I4(PPh2-)4] cluster unit.
