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:
wherein R1, R2, R4 and R5 independently represent each a hydrogen atom or a monovalent organic group optionally having one or more 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.
它旨在提供新颖的含氨基杂环衍生物,其在可见光区域具有广泛的吸收区,并适用于具有高光电转换效率的光电转换染料的敏化剂,以及使用相同的光电转换材料、光电转换电极和光电转换电池。即,表示为以下一般式(I)并在末端含有氨基的杂环衍生物:其中R1、R2、R4和R5分别独立地表示氢原子或一个或多个取代基的一价有机基;R3表示能够结合到显示半导体特性的无机多孔材料的锚定基团;X表示二价芳香碳氢基团或两个或更多个二价或更高的芳香碳氢基团的组合;Y表示具有硫原子的二价芳香杂环基团;Z表示二价芳香杂环基团、二价芳香碳氢基团、二价不饱和碳氢基团或其组合;m为1至3的整数。
