TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: The method of preparing the mesoporous titania film, further comprises sensitizing the mesoporous titania film with a dye or other chromophore molecules, where the step of sensitizing further comprises soaking the mesoporous titania film in a dye solution comprising acetonitrile/tert-butyl alcohol (50:50 vol/vol.%) containing a ruthenium complex of formula (Ru(L1-L2(NCS)2)) (3x 10-4 M). The step (f) further comprises solvent washing at 50 degrees C. The step (e) comprises dip-casting or spin-casting, where the substrate comprises a glass slide having a fluorinated tin oxide coating that is electrically conducting.L1 = 2,2'-bipyridyl-4,4'-dicarboxylic acid andL2 = 2,2'-bipyridy-4,4'- ditetrabutylammoniumcarboxylate.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The alcohol is ethanol and the organic acid is acetic acid.    TECHNOLOGY FOCUS - POLYMERS - Preferred Method: The step (a) further comprises converting terminal hydroxyl groups of poly(ethylene glycol) blocks of poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) triblock copolymer to terminal phosphate ester groups, where the step of converting further comprises mixing the poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) triblock copolymer with dimethyl phosphite. The step (c) further comprises solvent washing comprising the step of undergoing hydrolysis at terminal phosphate ester groups of the mesoporous silica material attached to the phosphonated triblock copolymer template at 50-80 degrees C. Preferred Components: The copolymer of the template is a poloxamer, which is acid cleavable. EXAMPLE - Phosphonated triblock copolymer (5 g) and dimethyl phosphite (100 ml) were mixed in a three-necked flask and refluxed at 150 degrees C under nitrogen for 4 hours. The methanol produced in the reaction was removed. The mixture was cooled under nitrogen and the unreacted dimethyl phosphite was removed using vacuum, producing a waxy residue of phosphonated triblock copolymer template. The template (4.15 g) was mixed with distilled water (200 ml) under stirring. 12 M hydrochloric acid (40 ml) and tetraethyl orthosilicate (18.22 g) were added and the reaction mixture was stirred at 40 degrees C for 20 hours. The material was aged for 24 hours at 80 degrees C. The solution was filtered and the solid mesostructured material was dried at 90 degrees C for 24 hours. The mesostructured material (1 g) was stirred in a 1:1:1 ratio of acetone, ethanol and diethyl ether at 50 degrees C for 24 hours followed by 3 washes with ethanol (20 ml) and then filtered and dried for 24 hours at 80 degrees C to produce mesoporous materials.
