We have investigated the nonlinear optical properties of one-dimensional metal complexes, and found that d8 transition metal complexes with dionedioxime show large third order nonlinear optical properties and ultrafast response. In this study, we examined to fabricate a one-dimensional superlattice using these dioxime metal complexes with a purpose of controlling its electronic state of the one-dimensional system. Alternative deposition of two metal dioxime complexes on an alkali halide cleaved surface gave a one-dimensional supper-lattice consisting of atomic wires of which constituents are arranged artificially by several kinds of metal. Their optical properties were examined by electro absorption spectrum measurements. Spectral peak shifts indicate that hetero-junctions between two different central metals are formed in the superlattice structures. Their nonlinear optical properties were also examined in related to this linear chain structure.
