Abstract: Ferrocene-containing ploynuclear metal complexes M(Fe-C(CH_3)=N N=CSSR)_2 (M=Ni~(2+), Cu~(2+), Zn~(2+), Pd~(2+), Co~(2+), Cd~(2+), R=CH_3, CH_2φ) have been synthesized and characterized by cyclic voltummetry. It has been found that this kind of complexes can quench the luminescence of [Cr(bpy)_3]~(3+) efficiencily. The Stern-Volmer plot is linear and yield the bimolecular quenching rate constants in order of 10~8～10~9 dm~3·mol~(-1)·s~(-1). The quenching process is carrid out through electron transfer and energy transfer mechanism.
