[6-(Furan-2-yl)-2,2′-bipyridine]bis(triphenylphosphine) Copper(I) Tetrafluoroborate

A new heteroleptic Cu(I) complex, [Cu(L)(PPh3)2][BF4] (L = 6-(furan-2-yl)-2,2′-bipyridine; PPh3 = triphenylphosphine), was successfully synthesized and characterized. Its molecular structure was determined using X-ray crystallography, and NMR as well as HR-ESI-MS data confirm the compound’s integrity in solution. The complex exhibits emission solely in the solid state (λem = 576 nm) and demonstrates a photoluminescence quantum yield of 2.5%.
