摘要: Abstract Some copper(I) complexes with imonopyridine ligands [Cu( L 1 )(PPh 3 ) 2 ]X (X = Cl ( 1a ), ClO 4 2a BF 3a PF 6 4a )) and 1b 2b 3b 4b [Where = N-(2-pyridylmethylene)-4-(bromo)aniline, = N-(2-pyridylmethylene)-4-(ethynyl)aniline; PPh = triphenylphosphine] have been synthesized characterized on the basis of their elemental analyses, IR, H NMR 31 P spectral studies. The representative ]ClO ]PF were by single crystal X-ray analysis which reveals a distorted tetrahedral geometry around each center. Quasireversible redox behavior is accounted for all corresponding to Cu(II)/Cu(I) couple. Photophysical properties indicate that insertion ethynyl (C C H) functionality iminopyridine induces pronounced red shift in absorption emission wavelength complexes.
