<p>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 '-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 '-conjugated-cyclic-compound residue represented by Ar 1 and has an sp2 hybridized orbital: (wherein Ar 2 represents a divalent group having a residue of a '-conjugated cyclic compound; X1 represents a direct bond or a divalent group selected from the group consisting of NQ1-,-PQ 2-, 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 E 1 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.))</p> |
