Abstract

Two new ferrocenyl derivatives, ( z)-[1-(benzylthio)-1-(4′,4′-dimethyl-oxazolinyl)-2-ferrocenyl]ethylene ( 3) and ( Z)-[1-(benzylsulfino)-1-(4′,4′-dimethyloxazolinyl)-2-ferrocenyl]ethylene ( 4) have been synthesized. On complexation with PdCl 2 these yield new bimetallic complexes 5 and 6 respectively. Non-linear optical properties measured by the EFISH technique show an enhanced molecular hyperpolarizability upon complexation, leading to higher values for β 0.
