Abstract

The search for materials with a large third-order optical nonlinear susceptibility and fast response has been one of the most important subjects for developing future optoelectronic devices. It is known that inorganic semiconductors and highly π-conjugated organic compounds are applicable for the third-order nonlinear optical material. While the most research effort has been both theoretically and experimentally concentrated on these materials, there are several experiments to find out new materials with superior optical nonlinearity. Recently, we have revealed that one-dimensional metal complexes show considerably large third-order optical nonlinearity that is mainly due to the electron delocalization in the linear metal chain.¹ In this study, we examined halogen doping effects on the third-order nonlinear optical properties for one-dimensional metal complexes.
