Abstract: Some copper(I) complexes of the formula [Cu(L)(PPh(3))(2)]X (1-4) [where L =2-phenyl-3-(benzylamino)-1,2-dihydroquinazolin-4(3H)-one; PPh(3) = triphenylphosphine: X = Cl(-), NO(3)(-), ClO(4)(-) and BF(4)(-)] have been prepared and characterized on the basis of elemental analysis, IR, UV-Vis and (1)H 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.
