TECHNOLOGY FOCUS - ELECTRONICS - Preferred Components: The photoanode comprises a transparent electrode (101); a metal oxide layer formed on a surface of the transparent electrode; and the dye for a photoelectric device adsorbed to a surface of the metal oxide layer opposite the transparent electrode. The transparent electrode is a transparent substrate coated with a conductive material. The photoanode further comprises at least one dye (D1). The surface area of the metal oxide layer to which the dye is adsorbed has nano-structure including nanotube, nanowire, nanobelt, or nanoparticle.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation(disclosed): The compound (I) is prepared by diluting a compound containing at least one quaternary ammonium group such as n-hexadecyltrimethylammonium hydroxide, in a solvent; mixing the diluent containing the quaternary ammonium groups with RuL'2(NCS)2(Bu4N)2 having two tetrabutylammonium (TBA) group substituents (where L' is ligand and Bu is n-butyl). Preferred Components: The dye (D1) is selected from ruthenium complexes; xanthine-based dyes; cyanine-based dyes; basic dyes; porphyrin-based compounds; azo dyes; phthalocyanine compounds; Ru trisbipyridyl complexes; anthraquinone-based dyes or polycyclic quinine-based dyes. The xanthine-based dyes include rhodamine B, Rose bengal, eosin, or erythrosine; the cyanine-based dyes include quinocyanine or cryptocyanine; the basic dyes include phenosafranine, capri blue, thiosine, or methylene blue; and the porphyrin-based compounds include chlorophyll, zinc porphyrin, or magnesium porphyrin. Preferred Definitions:    m+n=3-4;    A=tetrabutylammonium;    A'=tetramethylammonium, n-hexadecyltrimethylammonium or benzyltrimethylammonium;    m=2;    n=1.    SPECIFIC COMPOUNDS - ((Tetrabutylammonium)(tetramethylammonium)(2,2')bipyridinyl-4,4'-dicarboxylato)((tetrabutylammonium)(2,2')bipyridinyl-4-carboxylic acid-4'-dicarboxylato)(Ru)(NCS)2 (Ia);((tetrabutylammonium)(trimethylhexadecylammonium)(2,2')bipyridinyl-4,4'-dicarboxylato)((tetrabutylammonium)(2,2')bipyridinyl-4-carboxylic acid-4'-dicarboxylato)(Ru)(NCS)2; and ((tetrabutylammonium)(trimethylbenzylammonium)(2,2')bipyridinyl-4,4'-dicarboxylato)((tetrabutylammonium)(2,2')bipyridinyl-4-carboxylic acid-4'-dicarboxylato)(Ru)(NCS)2 are specifically claimed as (I).    EXAMPLE - Benzyltrimethylammonium hydroxide solution (12.55 mg) was poured into a flask at room temperature and diluted with methanol (20 ml). Ru(2,2'-bipyridyl-4,4'-dicarboxylic acid)2(NCS)2(Bu4N)2 dye (0.03 mmol)(where Bu is n-butyl) was added to the flask, and the mixture was stirred and allowed to react for 2 hours. Then, the solvent was removed from the dye solution of cis-bis-isothiocyanato-bis(4,4-dicarboxylic acid-2,2-bipyridine)ruthenium(II)(tetrabutylammonium)2(benzyltrimethylammonium)1. Subsequently, cis-bis-isothiocyanato-bis(4,4-dicarboxylic acid-2,2-bipyridine)ruthenium(II)(tetrabutylammonium)2(benzyltrimethylammonium)1 was dissolved in mixed solvent (100 ml) (comprising acetonitrile (10 vol.%) and tertiary-butanol(90 vol.%)), to obtain ((tetrabutylammonium)(tetramethylammonium)(2,2')bipyridinyl-4,4'-dicarboxylato)((tetrabutylammonium)(2,2')bipyridinyl-4-carboxylic acid-4'-dicarboxylato)(Ru)(NCS)2 (Ia).
