TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compound: The electron accepting compound is fullerene. The host is calixarene which has hydrophobic upper end and ionic hydrophilic functional group containing lower end. The fullerene and calixarene are laminated on electroconductive substrate, and host-guest complex is formed when calixarene and fullerene are bonded in the ratio of 2:1. The complex has a surface charge opposite to the hydrophilic functional group of calixarene. Electron donor which has the hydrophilic functional group of calixarene and functional group of opposite electric charge is laminated on the host-guest complex. The host is cyclodextrin when electron donor is polymer which consists of repeating unit having side chain of formula (1).n = 5-15; andM = 2H, zinc or magnesium. SPECIFIC COMPOUNDS - Cyclodextrin is beta-cyclodextrin, fullerene is C60 and calixarene is homo oxa Calyx (3) arene.    EXAMPLE - N,N-dimethyl propane diamine was added to triester of calyx (3) arene and precursor of calyx (3) arene was synthesized by aminolysis. N-methylation of the precursor was carried out using dimethyl sulfuric acid and calyx (3) arene having quaternary amine group in the terminal was synthesized. C60 fullerene (72 mg) was mixed with aqueous solution of calyx (3) arene, stirred and ultrasonicated. Fullerene remaining without complexing was removed and aqueous solution of the complex which consists of calyx (3) arene and C60 fullerene was prepared. A porphyrin monomer was copolymerized with 2-acrylamide-2-methyl propane sodium sulfonate, and porphyrin polymer having anionic hydrophilic functional group and porphyrin structure in side chain was synthesized. An indium tin oxide substrate was hydrophilized, washed and pretreated. The substrate was cleaned using ultra pure water and immersed in aqueous solution of hydrogen peroxide and ammonia and further washed and dried. The substrate was immersed in the aqueous solution of calyx (3) arene-C60 fullerene complex for 10 minutes, washed and dried. The substrate was then immersed for 10 minutes in aqueous solution of trimethyl beta-cyclodextrin to which the aqueous solution of porphyrin polymer was added, and optoelectric transducer material was obtained. The material showed high fluorescence intensity, favorable photoelectric conversion property and high photoelectric current gain.
