Disclosed is an aromatic polymer containing one or more repeating units represented by the following formula (1). (In the formula, Ar 1 represents an arylene group having a fused ring structure or a divalent heterocyclic compound group having a π-conjugated system, and contains a group represented by the formula (2) below. This group is bonded to a carbon atom having a sp 2 hybrid orbital which is contained in a ring of the ring structure of the arylene group having a fused ring structure or the divalent heterocyclic compound group having a π-conjugated system represented by Ar 1 . (In the formula (2), E 1 represents a hydrogen atom, a halogen atom or a monovalent organic group; Ar 2 represents a group having a divalent π-conjugated cyclic compound residue, and two Ar 2 's may be the same as or different from each other; X 1 represents a divalent group selected from the group consisting of —NQ 1 -, —PQ 2 - and —BQ 3 -, and Q 1 -Q 3 independently represent a substituent; Z represents a direct bond or a divalent linking group, and two Z's may be the same as or different from each other; m i 's respectively represent 0 or 1; and in case where two X 1 's exist, they may be the same as or different from each other.) |
