Abstract:

Four novel Cu(I) complexes, [Cu(o-PYO)(PPh 3) 2]BF 4 (1), [Cu(o-PYO)(DPEphos)]BF 4 (2), [Cu 2(o-PYO)(PPh 3) 3(CH 3CN)](BF 4) 2 (3) and [Cu 2(o-PYO)(DPEphos) 2](BF 4) 2 (4) (o-PYO = 2,5- bis(pyridyl)-1,3,4- oxadiazole, PPh 3 = triphenylphosphine, DPEphos = bis(2- (diphenylphosphanyl) phenyl)ether), have been synthesized and characterized by 1H NMR, elemental analysis and single-crystal X-ray diffraction. The central cuprous ions in all complexes are surrounded by N and P atoms to form a distorted tetrahedral geometry, although one of the cuprous ions in complex 3 is coordinated by a PPh3 and an acetonitrile molecule due to the steric hindrance and weak coordination ability from monodentate PPh 3 ligand. The UV-vis absorption spectra in CH 2Cl 2 show the characteristic metal-to-ligand charge transfer (MLCT) absorption bands in the region of 360-480 nm. Four Cu(I) complexes exhibit yellow to orange-red phosphorescence with the emission maximum at 572, 577, 562 and 597 nm, respectively in the solid state.
