COMPOUND AND PHOTOELECTRIC CONVERSION ELEMENT USING SAME

Provided is a novel semiconductor material represented by formula (I). A1-B1-A1 (I) (In formula (I), A1 represents an electron-withdrawing group, B1 represents a divalent group including two or more structural units that constitute a Pi-conjugate system by being linked by a single bond, at least one of the two or more structural units is a first structural unit represented by formula (II), and at least one of the two or more structural units is a second structural unit represented by formula (II). And the remaining second structural unit other than the first structural unit is a divalent group including an unsaturated bond, an arylene group, or a heteroarylene group). (In formula (II), Ar1, Ar2, Y, and R are as defined in the description. ) 本发明提供一种下述式(I)所表示的新的半导体材料。A1-B1-A1(I)(式(I)中，A1表示吸电子性基团，B1表示包含由单键连结而构成π共轭系的2个以上的结构单元的2价基团，该2个以上的结构单元中的至少一个为下述式(II)所表示的第1结构单元，并且该第1结构单元以外的剩余的第2结构单元为包含不饱和键的2价基团、亚芳基或杂亚芳基)。(式(II)中，Ar1、Ar2、Y和R如说明书中所定义。)
