Paper Abstract

In this study highly polarizable metallic complexes of Cu2+, Ni2+, and Cr3+ of Bis(salicylaldiminato) Schiff base have been synthesized. These nonlinear optical materials showed second harmonic generation (SHG) when they were pumped 1.06 micrometers Nd:YAG laser. The intensity of the SH signal varied between the metal complexes, being strongest for Ni-salen complex. An extensive study for these materials has been done to characterize their optical quality and chemical stability. We report here the synthesis, nonlinear optical characterization, electron paramagnetic resonance, FTIR, thermogravimetric measurements and the second order nonlinear response of thermally robust series of donor- acceptor substituted Bis(salicylaldiminato) Ni2+, Cu2+, and Cr3+ complexes.
