F. Goldoni et al., SYNTHESIS AND CHARACTERIZATION OF POLY[3-(BUTYLTHIO)THIOPHENE] - A REGIOREGULAR HEAD-TO-TAIL POLYMER, Journal of materials chemistry, 7(4), 1997, pp. 593-596
Poly[3-(butylthio)thiophene] was obtained from 2,5-dibromo-3-(butylthi
o) thiophene according to the method of Kobayashi. The polymer was cha
racterized as having regioregular head-to-tail(HT) connections with si
gnificant extended conjugation length and optical properties, such as
solvatochromism and photoluminescence. The polymer is soluble in commo
n organic solvents and can easily form films.
