Outline of Final Research Achievements

This study was subjected to molecular recognition and controlled release of the reaction substrate using a porous coordination polymer showing a magnetic bistability at room temperature. Moreover, attempts to synthesize new complexes using a complex ligand containing a catalytic active porphyrins, aimed at active control of the catalytic activity which is based on the electronic state control by spin state of host framework.
