摘要

A new series of heterobimetallic complexes of the type [Cu(L _(1-3))(NC _5H _4CCRu(dppe) _2Cl)I] (3-5) and [Cu(L _(1-3))(NC _5H _4CCC _6H _4CCRu(dppe) _2Cl)I] (6-8) have been prepared by the reaction of trans-[RuCl(dppe) _2(CC-py-3)] (1) and trans-[RuCl(dppe) _2(CCC _6H _4CC-py-3)] (2) with copper(I) in the presence of Schiff base ligands L _(1-3) (where L _1 = N-(2-pyridylmethylene)phenylamine, L _2 = 4-bromo-N-(pyridylmethylene) phenylamine and L _3 = 4-nitro-N-(2-pyridylmethylene)phenylamine). All the complexes were characterized on the basis of elemental analysis, IR, UV-Vis, ~1H NMR, ~(31)P NMR and mass spectral studies. The electrochemical behavior of the complexes indicates a quasireversible redox behavior corresponding to Cu(I)/Cu(II) and Ru(II)/Ru(III) couples. All the complexes exhibit intra-ligand (π → π) fluorescence with a high quantum yield in dichloromethane. The second harmonic generation (SHG) efficiency of the complexes was measured by the Kurtz-powder technique, which indicates that all the complexes possess promising potential for the application as useful non-linear optical (NLO) materials.
