Jp. Lere-porte et al., Synthesis of regioregular poly(alkylbithiophene)s by an organometallic cross-coupling reaction., SYNTH METAL, 101(1-3), 1999, pp. 588-589
The synthesis of regioregular poly(alkylbithiophene) with more than 90 % of
head to tail coupling of bithiophene units is reported. The optical proper
ties of the new polymer has been studied and indicated high conjugation len
