Abstract:
1. A polymer compound comprising a constitutional unit represented by the following formula (6) and a constitutional unit represented by the following formula (1): wherein R 10 represents a hydrogen atom, an alkyl group, an aryl group, an aromatic heterocyclic group, an alkoxy group, an aryloxy group, an aralkyl group, an arylalkoxy group, a substituted amino group, a substituted carbonyl group, a substituted carboxyl group, a fluorine atom or a cyano group; Ar 10 and Ar 11 each independently represent an arylene group or an aromatic heterocyclic group; k and kk each independently represent an integer of 0 to 2, provided that Ar 10 and Ar 11 are not the group represented by the formula (1); a hydrogen atom in the group represented by each of Ar 10 and Ar 11 may be substituted by an alkyl group, an aryl group, an aromatic heterocyclic group, an alkoxy group, an aryloxy group, an aralkyl group, an arylalkoxy group, a substituted amino group, a substituted carbonyl group, a substituted carboxyl group, a fluorine atom or a cyano group; when there are a plurality of Ar 10 s and Ar 11 s, these may be the same or different, respectively and wherein R 1 represents an alkyl group, R 2 represents an aryl group, an aromatic heterocyclic group or a substituted amino group, R 3 represents a hydrogen atom, an alkyl group, an aryl group, an aromatic heterocyclic group, an alkoxy group, an aryloxy group, an aralkyl group, an arylalkoxy group, a substituted amino group, a substituted carbonyl group, a substituted carboxyl group, a fluorine atom or a cyano group, and two R 3 s may be the same or different, wherein the polymer compound further contains a constitutional unit derived from a phosphorescence emitting compound having an optionally substituted aryl group or an optionally substituted heteroaryl group as a substituent of a ligand thereof in which the total number of atoms other than a hydrogen atom of the substituent is 10 or more, and wherein the proportion of the number of adjacent bonds between the constitutional units represented by the formula (1) is less than 0.05 relative to the number of bonds between all constitutional units.
