Abstract:
A polymer compound comprising a constitutional unit represented by the following formula (1) and a constitutional unit represented by the following formula (X) and/or a constitutional unit represented by the following formula (Y),       [wherein, aX1 and aX2 each independently represent an integer of 0 or more. ArX1 and ArX3 each independently represent an arylene group or a divalent heterocyclic group and these groups each optionally have a substituent. ArX2 and ArX4 each independently represent an arylene group, a divalent heterocyclic group or a divalent group in which at least one arylene group and at least one divalent heterocyclic group are bonded directly to each other, and these groups each optionally have a substituent. When there are a plurality of ArX2 and a plurality of ArX4, each of them may be the same or different. RX1, RX2 and RX3 each independently represent an alkyl group, an aryl group or a monovalent heterocyclic group and these groups each optionally have a substituent. When there are a plurality of RX2 and a plurality of RX3, each of them may be the same or different.] ArY1  (Y) [wherein, ArY1 represents an arylene group, a divalent heterocyclic group or a divalent group in which at least one arylene group and at least one divalent heterocyclic group are bonded directly to each other, and these groups each optionally have a substituent.].
