| 摘 要： | Introduction Copper(I) complexes have received much attention for their being less expensive and environmentally friendly, various coordination geometry, rich photo-chemical and photophysical properties.1-7 It is well known that copper complexes with diimine (2,2'-bipy- ridine, 1,10-phenanthroline and their substituted deriva-tives designated as diimine) generally exhibit low en-ergy metal-to-ligand charge-transfer (MLCT) states lo-cated in the regions of 350650 nm (e ≈ 103—104 dm3昺ol-1昪…

| Abstract: | The mono- and binuclear Cu(I) complexes with substituted 2,2'-bipyridine and iodide ligands, CuL2]BF4 (L=4-methoxycarbonyl-6-(4-methylphenyl)-2,2'-bipyridine (a), 6-(4-hydroxymethylphenyl)-2,2'-bipyridine (b) and 6-(4-methoxylphenyl)-2,2'-bipyridine (c)) and Cu2(-I)2L2] were prepared, and the crystal structures of the com-plexes were obtained from signal-crystal X-ray diffractional analysis. The spectroscopic properties of the complexes in dichloromethane are dominated by low energy MLCT bands from 360 to 650 nm. The electrochemical studies of mononuclear complexes reveal that the complexes have stable copper(I) state. |
