NOVEL AMINO GROUP-CONTAINING HETEROCYCLIC DERIVATIVES AND SENSITIZING DYES FOR PHOTOELECTRIC CONVERSION CONTAINING THE HETEROCYCLIC DERIVATIVES

摘要

It is intended to provide novel amino group-containing heterocyclic derivatives, which have a broad absorption zone in the visible region and are suitable for sensitizing dyes for photoelectric conversion having a high photoelectric conversion efficiency, and photoelectric conversion materials, photoelectric conversion electrodes and photoelectric conversion cells using the same. Namely, a heterocyclic derivative represented by the following general formula (I) and containing an amino group at the terminus: (1) wherein R₁, R₂, R₄ and R₅ independently represent each a hydrogen atom or a monovalent organic group optionally having a substituent; R₃ represents an anchor group capable of binding to an inorganic porous material showing semiconductor characteristics; X represents a divalent aromatic hydrocarbon group or a combination of two or more aromatic hydrocarbons being divalent or higher; Y represents a divalent aromatic heterocyclic group having a sulfur atom; Z represents a divalent aromatic heterocyclic group, a divalent aromatic hydrocarbon group, a divalent unsaturated hydrocarbon group or a combination thereof; and m is an integer of from 1 to 3.
