Patent ID: 8779277

Claim:
A method of transferring electrons with a light energy conversion material comprised of a porous material including an electron donor in a skeleton thereof, and an electron acceptor disposed in at least one portion among a pore, the skeleton and the outer circumference of the porous material, wherein the porous material including the electron donor in the skeleton thereof is a silica porous material comprised of silicon atoms chemically bonded with an organic group, the method comprising: absorbing light energy by the organic group of the silica porous material and transferring electrons excited by the light energy from the organic group of the silica porous material to the electron acceptor, wherein the organic group is the electron donor and is a molecule selected from the group consisting of 1,1-bi-2-naphthol, 1,3-di(N-carvazolyl)propane (DCzPr), 1,4-di(N-carvazolyl)butane (DCzBu), 1,4-diazabicyclo[2,2,2]octane, 2,3-dihydroxy-naphtol, 2,7-dihydroxy-naphthol, 2-naphthol, Cu(2,9-diphenyl-1,10-phenanthroline) 2+ , di(N-carvazolyl)methane (DCzMe), meso-2,4-di(N-carvazolyl)pentane (m-DCzPe), Mg(phthalocyanine) 4+ , N,N,N′,N′-tetramethyl-p-phenylenediamine, N,N,N′,N′-tetramethylbenzidine, N,N-diethylaniline, N,N-dimethylaniline, N-ethyl-carbazole (EtCz), Rh 2 (1,3-diisocyanopropane) 4 2+ , Ru(2,2′-bipyridine) 3 2+ , Tetrakis(dimethylamino)ethylene (TDAE), trans-1,2-di(N-carvazolyl)cyclobutane (DCzCBu), Zn(tetra(N-methylpyridinium)porphyrin) 4+ , a Zn porphyrin complex, Zn(tetraphenylporphyrin), Zn(octaethylporphyrin), a Zn phthalocyanine complex, anthracene, indene, oxadiazole, oxazole, quadricyclane, diazabicyclooctane, diphenylethylene, triethylamine, triphenylmethane, trimethoxybenzene, naphthalene, norbornadiene, hydrazone, pyrene, phenanthrene, phenothiazine, perylene, methoxynaphthalene and biphenyl.
