摘要：

A series of copper(II) and copper(I) complexes, [CuX2L] (1-6) and [CuL2](CuX2) (7-12) (X = Cl, Br; L = 2-R-9-R'-1,10-phenanthroline, dpp: R = R' = Ph; npp: R = naphthyl, R' = Ph; drip: R = R' = naphthyl) were synthesized and characterized by elemental analysis, UV/Vis and IR spectroscopy, and Xray crystal diffraction (for 1, 3, 6, and 12). The copper(II) complexes are four-coordinate with one phenanthroline ligand and two halogen atoms, whereas the copper(I) complexes are tetrahedrally coordinated by two bidentate phenanthroline ligands. Cyclic voltammetry studies of the Cu-I complexes in CH2Cl2 reveal that bulky groups in the 2,9-positions have significant effects on the redox potential of the Cu-II/I couple, which is more positive for the complexes with the drip ligand than those with the dpp and npp ligands.
