EXAMPLE - Trimethyloctadecylammonium chloride (1.83 g) was dissolved in a mixed liquid of water (100 ml) and a 6 M aqueous solution of sodium hydroxide (10 g) to obtain a mixed solution. Then, 4,4'-bis(triethoxysilyl)biphenyl (2 g) was added dropwise into the obtained mixed solution while stirring at room temperature. Then, the reaction solution was heated to obtain a silica porous material modified by a biphenyl group (BiPh-HMM) containing the surfactant. After work up, BiPh-HMM crystalline powder was obtained.4,4'-Bipyridyl (1.80 g), and (3-iodopropyl)trimethoxysilane (7.02 g) were dissolved in acetonitrile (25 ml) in an argon atmosphere to obtain a mixed solution. Then, the obtained mixed solution was stirred at 40degrees C for 7 hours. After work up, 4,4'-bipyridine derivative (N,N'-Bis(3-(trimethoxysilanyl)propyl)-4,4'-bipyridinium diiodide)(7.62 g) was obtained. The BiPh-HMM crystalline powders (0.4 g) was added to a solution prepared by dissolving the 4,4'-bipyridine derivative (100 mg) in water-containing acetonitrile (8 ml). Then, the mixture was treated with ultrasonic waves at room temperature for 1 minute. After work up, crystalline powder of BiPh-HMM modified by viologen (SiVSi(I)-BiPh-HMM) (0.462 g) was obtained, and showed pore surface area of 699.48 m2/g, the pore diameter of 23 Angstrom , and pore volume of 0.40 cc.
