Abstract:
1. A light energy conversion material, comprising: 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 covalently bonded with an organic group, wherein the organic group is the electron donor, and absorbs light energy and transfers electrons excited by the light energy to the electron acceptor, and wherein the organic group 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)
