Research Abstract

The following three results relevant to molecular device have been obtained. 1) construction of 2-dimensional wiring system: Hexaarylbenzene turns out to be effective 2-dimensional linker for molecular wiring. 2) mechanism of photoswitching: Dependence of performance on the metal and ligand has been analyzed by quantum chemical method. The occurence is dependent on a process in the final part. 3) metal complexes with extended pi-conjugated systems: Mon-, di- and tetra-nuclear porphyrin complexes are prepared and their properties relevant to stacking, switching of luminescent properties, linker performance, and 2-dimensional M-M interaction have been studied.
These findings would lead to development of molecular devices in the future.
