(3) New photoreaction of Re(I) complex and the application for metal-assembled complexes

Photo-induced ligand exchange reaction of Re(I) complex was discovered and the mechanism has been investigated. Moreover, it was found that 1D-oligomeric and macrocyclic metal complexes could be formed by applying the ligand exchange reaction (Fig. 3 and 4).
