A novel light harvesting system that captures long-wavelength light of sunlight by the use of hole transfer was newly investigated. Ga phthalocyanine(Ga(III)TMAPc(4+)(D)) and Ru porphyrin((RuDMPyMP2+)-D-II(A)) co-adsorbed reaction system on the synthetic nanosheet was examined as an artificial light harvesting system. By irradiating 660 nm light, where Ga(III)TMAPc(4+)(D) absorbs, to the system under a presence of PtCl62- as an electron acceptor, cation radical of (RuDMPyMP2+)-D-II(A) was produced despite that Ru porphyrin adsorbs only 413 and 533 nm light. The efficient hole transfer reaction from Ga(III)TMAPc(4+)(D)(+), that is generated from its excited state, to (RuDMPyMP2+)-D-II(A) takes place on the nanosheet.
