The electron donor is selected from at least one aromatic compound, peri-condensed aromatic compound, polycyclic aromatic compound, nitrogen-containing aromatic compound, sulfur-containing aromatic compound, aromatic vinyl polymer, aromatic amine compound, alkyl amine compound, nitro compound, metal complex having nitrogen-containing organic ligand, metal complex having cyclic ligand, metal complex salt, metal ion, rare-earth ion, halogen ion and/or their derivatives. The electron acceptor is selected from at least one quinone compound, aromatic compound having vinyl group, cyano group or nitro group, nitrogen-containing aromatic compound, organic compound having dicyanomethylene group, molecular metal complex containing organic compound having dicyanomethylene group as ligand, an organic compound having cyanoimino group, molecular metal complex containing cyanoimino group as ligand, fullerene, carbon nanotube, metal complex having nitrogen-containing organic ligand, metal complex having cyclic ligand, metal complex salt, metal ion, metal oxide, and/or their derivative. EXAMPLE - Trimethyloctadecylammonium chloride (1.83 g) was dissolved in the mixture of water (100 ml) and 6M aqueous solution of sodium hydroxide (10 g) to obtain a mixed solution. Then, 4,4'-triethoxysilylbiphenyl (2 g) were added dropwise while stirring at room temperature. Then irradiation with ultrasonic waves for 20 minutes and the stirring were repeated to the mixed solution. Simultaneously the mixed solution was stirred for 24 hours at room temperature to obtain reaction solution. After that, the reaction solution was left at rest at 98degrees C for 48 hours. The reaction solution was heated to obtain silica porous material modified by biphenyl group (BiPh-HMM) containing the surfactant. Subsequently, the BiPh-HMM containing the surfactant was suspended in mixed liquid containing ethanol (260 ml) and concentrated hydrochloric acid (11.7 g) to obtain suspension solution. The suspension solution was stirred while heating at 70degrees C for 7 hours to extract the surfactant from BiPh-HMM containing the surfactant. After that, the suspension solution was filtered. The obtained white powders were washed with ethanol and vacuum-dried to obtain BiPh-HMM crystalline powders (a1). The powder (a1) (1g), 2,2'-bipyridine derivative (143 mg) having (A-(9-(3-(trimethoxysilanyl)propyl sulfanyl)butyl)-4-methyl-2,2'-bipyridinyl group, and acetonitrile (20 ml) were mixed in a sample tube. The mixture was irradiated with ultrasonic waves for 1 minute. The mixture was then heated at 70degrees C for 2 hours to obtain powders. Subsequently, the obtained powders were separated by filtration, washed with ethanol and ion-exchange water, and then dried in vacuum to obtain BiPh-HMM powders (977.6mg) into which bipyridine was introduced HiPy'-BiPh-HMM (a2). The powder (a2) (50 mg), (Ru(4,4'-dimethyl-2,2'-bipyridine)2Cl2:2H2O (3 mg) and methanol (20 ml) were mixed. Then, the mixture was heated at 70degrees C for 15 hours to obtain powders. The obtained powders were separated by filter, washed with methanol, and then dried in vacuum to obtain (Ru(4,4'-dimethyl-2,2'-bipyridine)2BiPy'-BiPh-HMM as light energy conversion material. The material efficiently collect the light and efficiently transferred the light so that efficient energy transfer was obtained.
