摘要：
Some copper(I) complexes of the formula [Cu(L)(PPh3)(2)]X (1-4) [where L =2-phenyl-3-(benzylamino)-1,2-dihydroquinazolin-4(3H)-one; PPh3 = triphenylphosphine: X = Cl-, NO3-, ClO4- and BF4-] have been prepared and characterized on the basis of elemental analysis, IR, UV-Vis and H-1 NMR spectral studies. The representative complex of the series 4 has been characterized by single crystal X-ray diffraction which reveal that in the complex the central copper(I) ion assumes the irregular distorted-tetrahedral geometry. Cyclic voltammetry of the complexes indicate a quasireversible redox behavior corresponding to Cu(II)/Cu(I) couple. All the complexes exhibit intraligand (pi -> pi*) fluorescence with high quantum yield in dichloromethane solution. (C) 2011 Elsevier Ltd. All rights reserved.
