Abstract
Disclosed is an aromatic polymer containing one or more repeating units represented by the following formula (1). (In the formula, Arrepresents 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 sphybrid 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. (In the formula (2), Erepresents a hydrogen atom, a halogen atom or a monovalent organic group; Arrepresents a group having a divalent π-conjugated cyclic compound residue, and two Ar's may be the same as or different from each other; Xrepresents a divalent group selected from the group consisting of —NQ-, —PQ- and —BQ-, and Q-Qindependently 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's respectively represent 0 or 1; and in case where two X's exist, they may be the same as or different from each other.)
