Title:
SPIROBIFLUORENE DERIVATIVE, DYE FOR PHOTOELECTRIC CONVERSION ELEMENTS, SEMICONDUCTOR ELECTRODE USING SAME, PHOTOELECTRIC CONVERSION ELEMENT, AND PHOTOELECTROCHEMICAL CELL
Document Type and Number:
WIPO Patent Application WO/2013/121835
Kind Code:
A1
Abstract:
As a dye for photoelectric conversion elements, which has excellent photoelectric conversion characteristics, at least one compound represented by general formula (1) and having a spirobifluorene skeleton is used. (In formula (1), each of R1 and R2 independently represents a hydrogen atom, a substituted or unsubstituted alkyl group or alkoxy group, a hydroxy group or a substituted or unsubstituted aryl group; Z represents a linking group of a π-conjugated system; and X represents an organic group having an acidic group.)
