Abstract
Provided are a thiophene-containing compound represented by the following formula (X-1), and an organic electroluminescent device that includes a pair of electrodes and an organic compound layer disposed therebetween. The organic compound layer includes a charge-transporting polyester having a repeating structure containing at least one structure selected from the structures represented by the following formulae (I-1) and (I-2) as its partial structure. In formula (X-1), Ar1 represents a substituted or unsubstituted monovalent aromatic group; and R1 to R4 each independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group; and n′ is an integer of 1 to 5.
