Electroluminescent devices have, as the active layer, a polymer comprising a poly(3-substituted thiophene), the 3-substituent of which is an alkyl, cycloalkyl,alkoxyalkyl, fluorocarbon, siloxyl or heteroorganic group, the poly (3-substitued thiophene) having a head-to-tail ratio of at least about 80 percent. Such devices give better electroluminescent performance than similar devices using a poly(3-substituted thiophene) having a lower head-to-tail ratio.

La couche active de dispositifs électroluminescents est un polymère comprenant un poly(thiophène substitué en position 3), dont le substituant en position 3 est un groupe alkyle, cycloalkyle, alcoxy, cycloalcoxy, alcoxyalkyle, fluorocarbone, siloxyle ou hétéro-organique, le poly(thiophène substitué en position 3) ayant un rapport tête/queue d'environ 80 % au moins. Ces dispositifs présentent de meilleurs performances électroluminescentes que des dispositifs similaires faisant intervenir un poly(thiophène substitué en position 3) ayant un rapport tête/queue plus faible.
