Synthesis,Crystal Structure and Photophysical Properties of Cu(Ⅰ) Complexes Containing 2,5-Bis(pyridyl)-1,3,4-oxadiazole

         

摘要

Four novel Cu(Ⅰ) complexes,[Cu(o-PYO)(PPh3)2]BF4(1),[Cu(o-PYO)(DPEphos)]BF4(2),[Cu2 (o-PYO)(PPh3)3(CH3CN)](BF4)2(3) and [Cu2(o-PYO)(DPEphos)2 ](BF4)2(4) (o-PYO=2,5bis(pyridyl)-1,3,4-oxadiazole,PPh 3=triphenylphosphine,DPEphos=bis(2-(diphenylphosphanyl)phenyl)ether),have been synthesized and characterized by 1 H 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 PPh3 ligand.The UV-vis absorption spectra in CH2Cl2 show the characteristic metal-to-ligand charge transfer (MLCT) absorption bands in the region of 360-480nm.Four Cu(I) complexes exhibit yellow to orange-red phosphorescence with the emission maximum at 572,577,562 and 597nm,respectively in the solid state.
