NOVEL COPOLYMER, ORGANIC SEMICONDUCTOR MATERIAL, AND ORGANIC ELECTRONIC DEVICE, PHOTOELECTRIC CONVERSION ELEMENT AND SOLAR CELL MODULE USING THE ORGANIC SEMICONDUCTOR MATERIAL
PROBLEM TO BE SOLVED: To provide a novel copolymer which is highly soluble, has absorption in a long wavelength region, and is suitable for a photoelectric conversion element.;SOLUTION: The copolymer has a repeating unit represented by formula (1) and contains as a terminal group an aryl group which may have a substituent. (R1 is a substituted/unsubstituted alkyl group, a substituted/unsubstituted alkenyl group, or a substituted/unsubstituted aryl group, and R2-R5 are each independently H, a halogen atom, a substituted/unsubstituted alkyl group, a substituted/unsubstituted alkenyl group, or a substituted/unsubstituted aryl group);COPYRIGHT: (C)2015,JPO&INPIT
