Optical limiting efficiency of an electroactive bis-iminopyridine ligand and its zinc complex

Abstract

An electroactive based bis-iminopyridine ligand has been synthesized by a condensation reaction between (4-(6,7-dimethyldithio-tetrathiafulvalene)-aniline) with 2,6-diformylpyridine. The complexation of this ligand with ZnCl 2 afforded a tetrahedral neutral Zinc metal complex. optical measurements of these structures have given good results in picosecond regime. The nonlinear absorption of the ligand was significantly enhanced upon complexation with ZnCl 2 . This prompted us to conduct the experiment of optical limiting at wavelength 532nm. The nonlinear absorption properties of these structures were studied and compared to the reference material C 60 . Full Text: PDF References V. Rosso, J. Loicp, Y. Renotte, Y.
