PHOTO ENERGY-TO-ELECTRICAL ENERGY TRANSFORMATION SERIES USING ITO ELECTRODE CHEMICALLY MODIFIED WITH PORHYRIN- FULLERENE-COMBINED MOLECULE

摘要

PROBLEM TO BE SOLVED: To provide a photo energy-to-electrical energy transformation series, which remarkably improves the quantum efficiency upon generating photocurrents. ;SOLUTION: The photo energy-to-electrical energy transformation series includes a single molecule film, which is formed by self-organizing at least one compound selected among a compound group represented by the general formula (A) on the electrode surface of an indium-tin oxide(ITO) via a covalent bond symbolized by Bin. (Bin. Stands for O₃Si-, carboxylic acid ester, or phosphoric acid ester. Each of X¹-X³ stands for a group selected among single bond compounds -N-H-CO-,-CO-NH-,-Ph-,-O-, or -CO-O-. n stands for a natural numbers among 1 to 20. Ar stands for a phenyl group, which may include a substituent of a heavy molecular weight. M stands for 2H (hydrogen) or Zn (zinc). A fullerene derivative is selected among formulas (a) and (b), where the part consisting of fullerene is C₆₀ to C₉₀).;COPYRIGHT: (C)2003,JPO
