TECHNOLOGY FOCUS - ELECTRONICS - Preferred Battery: The photoelectric-conversion battery consists of photoelectric-conversion electrode, electrolyte layer and electroconductive counter electrode. The photoelectric-conversion electrode is formed by laminating photoelectric-conversion material on a transparent electrode.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred material: The inorganic porous material is an inorganic acid compound.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (disclosed): No preparation is given. Preferred Dye: The sensitizing dye contains aromatic compound (1) having amino group. Preferred Material: The photoelectric-conversion material contains sensitizing dye connected with inorganic porous material having semiconductor characteristics, and co-adsorption agent. Preferred Definitions:    X=optionally substituted (phenylene, naphthylene, anthrylene, phenanthrylene, biphenylene or terphenylene), preferably optionally substituted 1,4-phenylene;    Y=optionally substituted (phenylene, naphthylene, anthrylene or phenanthrylene), preferably optionally substituted 1,4-phenylene;    R3=carboxyl, phosphoric-acid group or sulfonic acid group, preferably carboxyl;    R1,R2,R4,R5=hydrogen, optionally substituted aliphatic hydrocarbon, aromatic hydrocarbon, aromatic heterocyclic group, halogen, cyano, isocyano, thiocyanate, isothiocyanate, nitro, hydroxyl, mercapto, amino, amide or -(A1)o-B-(A2)p-R6, where R4 is preferably electron-attracting group such as cyano, ester, amide or perfluoroalkyl;    A1,A2=O, NH or S;and    R6=hydrogen, optionally substituted monovalent aliphatic hydrocarbon, aromatic hydrocarbon, aromatic heterocyclic group, halogen, cyano, isocyano, thiocyanate, isothiocyanate, nitro, hydroxyl, mercapto, amino or amide.    SPECIFIC COMPOUNDS - 77 amino group-containing aromatic compounds are disclosed such as (2E)-2-cyano-3-(4-((E)-2-(4-(ethyl(methyl)amino)phenyl)vinyl)phenyl)acrylic acid, (2E)-2-cyano-3-(4-((E)-2-(4-(methyl(phenyl)amino)phenyl)vinyl)phenyl)acrylic acid, (2E)-2-cyano-3-(4-((E)-2-(4-(N-butyl(n-butyl)amino)phenyl)vinyl)phenyl)acrylic acid and (2E)-2-cyano-3-(4-((E)-2-(4-(N-butyl(propyl)amino)phenyl)vinyl)phenyl)acrylic acid.    EXAMPLE - 4-((E)-2-(4-(dimethylamino)phenyl)vinyl)-3-fluorobenzaldehyde (in g) (1) was added to 4-neck flask, heated and refluxed. Then, t-butyl cyanoacetate (1.67), morpholine (0.78) and toluene (60 ml) were added, cooled and solvent was distilled, to obtain N-(4-((E)-2-(2-fluoro-4-((1Z)-2-isocyanoprop-1-enyl)phenyl)vinyl)phenyl)-N,N-dimethylamine (1.3). The obtained acetate group-containing aromatic compound (1.3) and acetic acid (60 ml) were reacted. Then, hydrobromic acid (5.04) was added to reaction mixture, and stirred at room temperature. Ion exchange water (30 ml) was added to reaction solution, washed, extracted twice with methyl t-butyl ether (600 ml), and washed once with aqueous ammonia and twice with water. The washed solution was distilled under reduced pressure, to obtain aromatic compound (0.94) having amino group at the terminal. The obtained aromatic compound had broad absorption band in visible region. A photoelectric-conversion cell produced using the obtained aromatic compound as sensitizing dye, had excellent photoelectric conversion efficiency.
