Pc. Stein et al., NMR INVESTIGATION OF SOME CONJUGATED COPOLYMERS - POLY(3-ALKYL-CO-3,4-DIALKYLTHIOPHENE), Synthetic metals, 84(1-3), 1997, pp. 211-212
We have synthesised and characterised a series of soluble polyalkylthi
ophenes, based on the copolymerization of 3-alkylthiophene and 3,4-dia
lkylthiophene, wherein it is possible to modulate continuously electro
nic properties as the conjugation length and the energy gap.
