| Research Abstract |
A photo-induced electron transfer system using a phosphorescent platinum complex as a triplet-sensitizer was newly designed and synthesized. For the efficient use of light energy, we modify the platinum complex systems to more strongly absorb visible light. We also synthesized a platinum complex system having adsorptive functional group on an electrode. The results are summarized as follows. 1) We succeeded in the syntheses of a platinum complex linked with the phenyl acetylene unit linked with an electron donor and an electron acceptor. The excitation of the complex showed a long-lived charge separated state(ca 4μs) by photo-irradiation in the transient absorption spectra. 2) We succeeded to synthesize boron-dipyrromethene-containing platinum complexes. Their transient absorption spectra showed slightly long-lived charge separated states. 3) We also succeeded in the synthesis of a donor-acceptor-linked platinum complex possessing a terminal thioacetyl group.
