SPIROBIFLUORENE COMPOUND, COLORANT FOR PHOTOELECTRIC TRANSDUCER, AND PHOTOELECTRIC TRANSDUCER USING SAME

摘要

A colorant for a photoelectric transducer, containing a spirobifluorene compound represented by general formula (1). The colorant exhibits excellent photoelectric conversion characteristics and is useful not only for a semiconductor electrode for a photoelectric transducer but also for a photoelectric transducer and a photoelectrochemical cell. In general formula (1), R1 and R2 are each independently a hydrogen atom, a substituted or unsubstituted alkyl or alkoxy group, or a hydroxyl group; Z is a pi-conjugated linking group; and X is an organic group having an acid group.
