An aromatic graft polymer containing one or more kinds of repeating units represented by the following formula (1). (In the formula, Ar1 represents a divalent residue of a π-conjugated cyclic compound having a side chain represented by the following formula (2), the side chain being bonded to a carbon atom which is included in the ring structure of the divalent π-conjugated-cyclic-compound residue represented by Ar1 and has an sp2 hybrid orbital: (wherein Ar2 represents a divalent group having a residue of a π-conjugated cyclic compound; X1 represents a direct bond or a divalent group selected from the group consisting of NQ1-, -PQ2-, and -BQ3-, wherein Q1 to Q3 each independently represents a substituent; Z represents a direct bond or a divalent connecting group; k is an integer of 3 or larger; and E1 represents hydrogen, halogeno, or a monovalent organic group, provided that when two or more Ar2' s, X1' s, and Z's are present, then they each may be the same or different and when two or more side chains represented by the formula (2) are present, then they may be the same or different.))
一种芳香族接枝聚合物,含有下式(1)所代表的一种或多种重复单元。(式中,Ar1 代表具有下式(2)表示的侧链的π-共轭环状化合物的二价残基,侧链与 Ar1 所代表的二价π-共轭环状化合物残基的环结构中包含的碳原子键合,该碳原子具有 sp2 杂化轨道:(其中 Ar2 代表具有 π-共轭环状化合物残基的二价基团;X1 代表直接键或选自 NQ1-、-PQ2- 和 -BQ3- 组成的组的二价基团,其中 Q1 至 Q3 各自独立地代表取代基;Z 代表直接键或二价连接基团;k 是 3 或更大的整数;以及 E1 代表氢、卤素或一价有机基团,但当存在两个或多个 Ar2's、X1's 和 Z's 时,它们可以相同或不同,当存在两个或多个由式(2)代表的侧链时,它们可以相同或不同。))
