Nuevos copolímeros a base de indol

Abstract

Nuevos copolímeros a base de indol (ver figura en archivo de texto adjunto). La presente invención se refiere a un nuevo tipo de copolímeros de base indol de fórmula general (I), en la que R puede ser los heterociclos tiofeno y pirrol, DP son restos del agente oxidante que actúa como agente dopante. Para la obtención de los copolímeros se hace reaccionar indol con los heterociclos tiofeno o pirrol preferentemente a temperatura entre 25-30ºC en presencia de agente oxidante tal como el cloruro férrico, disueltos en cloroformo. En ambos casos se utilizan distintas relaciones molares de oxidante/monómero entre 1.5 y 5 y de comonómero/indol entre 1.5 y 9. Al final de la reacción se precipita el copolímero con una mezcla metanol/agua (1:1 en peso). Estos polímeros se caracterizan por presentar una marcada conductividad eléctrica y ser fácilmente solubles, lo que les hace ser aptos para diversas aplicaciones como conductores.
