Abstract
By the interaction of CuI with bis(2-pyridyl)phosphine oxides (2-Py)2RP(O) containing E-1-phenyl-2-aroylethenyl–C(Ph)=CHC(O)R′ (R′ = Ph, 2-thienyl) substituents, [Cu2I2L2] complexes are synthesized. Their structures are based on the rhomboidal Cu2I2 moiety whose copper atoms are N,N′-chelated by the indicated ligands. At room temperature, the crystalline samples of these complexes exhibit dark red photoluminescence (λmax = 680-685 nm) with a charge transfer from the Cu2I2 moiety to the ligand.
