By using a polymer compound comprising a constituent unit represented by the formula (1) and a constituent unit represented by the formula (2) in an organic layer of an organic photoelectric conversion device, photoelectric conversion efficiency can be enhanced.
[wherein R1 represents a hydrogen atom or a substituent. Y1 represents an oxygen atom, a sulfur atom or -N(R3)-. R3 represents a hydrogen atom or a substituent. Ring Z1 and ring Z2 represent each independently an optionally substituted aromatic carbocyclic ring or an optionally substituted heterocyclic ring.]
[wherein R2 is different from R1 and represents a hydrogen atom or a substituent. Y2 represents an oxygen atom, a sulfur atom or -N(R3)-. R3 represents a hydrogen atom or a substituent. Ring Z3 and ring Z4 represent each independently an optionally substituted aromatic carbocyclic ring or an optionally substituted heterocyclic ring.].
在有机光电转换装置的有机层中使用由式(1)表示的组成单元和式(2)表示的组成单元构成的聚合物化合物,可以提高光电转换效率。
[其中 R1 代表氢原子或取代基。Y1 代表氧原子、硫原子或 -N(R3)-。R3 代表氢原子或取代基。环 Z1 和环 Z2 各自独立地代表任选取代的芳香碳环或任选取代的杂环]。
[其中 R2 与 R1 不同,代表氢原子或取代基。Y2 代表氧原子、硫原子或-N(R3)-。R3 代表氢原子或取代基。环 Z3 和环 Z4 各自独立地代表任选取代的芳香碳环或任选取代的杂环]。
