Compound used for forming high-molecular compound

Abstract

The present invention provides a macromolecular compound by which the short-circuit current density and the photoelectric conversion efficiency are enhanced when the macromolecular compound is used in an organic layer contained in a photovoltaic cell. Specifically, the present invention provides a macromolecular compound having a structural unit represented by Formula (5): wherein R52 and R53 are the same as or different from each other and represent hydrogen atoms, halogen atoms, alkyl groups, alkyl oxygen radicals, alkyl sulfonium, aryl groups, aryl oxygen radicals, aryl sulfonium, aryl alkyl, aryl alkyl oxygen radicals, acyl groups, acyloxy, acylamino, imide groups, amidogen, substituted amino, substituted silicyl, substituted silicon alkyl oxygen radicals, substituted silicon alkyl harvard, silicon alkyl amine, univalent heterocyclic radical, heterocyclic oxygen radicals, heterocyclic sulfonium, aryl alkenyl, aryl alkynyl, carboxyl or cyan; W1 and W2 are the same as or different from each other and represent hydrogen atoms, halogen atoms, alkyl sulfonate base, aryl sulfonic acid ester base, aryl alkyl sulfonate base, boric acid ester residues, matte methyl, scales base, Phosphonic acid ester methyl, single halogenated methyl, boric acid residues, formyl groups, vinyl or organic tin residues.
