Abstract
Carbon—carbon bond-forming polymerization of 2-bromo-3-(3′,5′-di-t-butyl-4′-methoxyphenyl)-thiophene yields poly[3-(3′,5′-di-t-butyl-4′-methoxyphenyl)-2,5-thienylene] with regiospecific connectivity and a degree of polymerization of about six. Lewis-acid-moderated-cleavage of the methoxy groups on the pendant phenyl group yield the corresponding polyphenolic polymer, which is oxidized under solution conditions to yield the title polyradical. Poly[3-(3′,5′-di-t-butyl-4′-oxyphenyl)-2,5-thienylene] exhibits a strong, persistent electron spin resonance spectrum and a UV–visible spectrum consistent with formation of the pendant phenoxyl spin-bearing units. © 1999 John Wiley & Sons, Inc.
