| Research Abstract |
In this research we have succeeded to synthesize new iridium complexes bearing bidentate organic ligands with an N-atom in their chelate framework, which resulted from N-atom insertion reaction initiated by photolysis of iridium(III)?azido complexes. Also, the investiga- tion of their chemical reactivities toward nucleophiles and/or electrophiles revealed the formation of new N-containing organic compounds, as well as the alkylation of the inserted N-atom followed by the complete transfer of the imino group from the metal center. Furthermore, photolysis of the related azido complexes afforded tetrazolate ligands, which could bridge two metal centers giving homo- and heterodinuclear metal complexes. The systematic investigation of their molecular structures in the solid states and in solution led to guide principles for molecular design of functional materials.
