Provided is a polymer compound useful for production of a light emitting device excellent in external quantum yield. The polymer compound includes a constitutional unit represented by the formula (1): wherein aand arepresent 0 or 1, Arand Arrepresent an arylene group or the like, and in each of Arand Arat least one atom adjacent to an atom forming a bond to the constitutional unit adjacent to the each of Arand Arhas an alkyl group or the like as a substituent, Arrepresents a phenylene group, Arrepresents an arylene group or the like, R, Rand Rrepresent an aryl group or the like, and when ais 0, Rrepresents an aryl group in which two or more rings are condensed (the number of carbon atoms constituting the rings of the aryl group is 10 or more) or the like.

Polymer compound and light-emitting device using the same

A method for producing a 1,2,4-triazole compound involves reacting an amide compound represented by formula (2) with a hydrazide compound represented by formula (3) in a solvent in the presence of a Lewis acid and a Lewis base, thereby obtaining a 1,2,4-triazole compound represented by formula (1): Rrepresents an alkyl group, a cycloalkyl group, an alkoxy group, a cycloalkoxy group, an aryl group, an aryloxy group, a monovalent heterocyclic group or a substituted amino group, Rand Reach independently represent a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group, a monovalent heterocyclic group or a substituted amino group, and Ring A and Ring B each independently represent an aromatic hydrocarbon ring or an aromatic heterocyclic ring.
