NMR investigation of some conjugated co-polymers: Poly(3-alkyl-co-3,4-dialkylthiophene)

We have synthesised and characterised a series of soluble polyalkylthiophenes, based on the copolymerization of 3-alkylthiophene and 3,4-dialkylthiophene, wherein it is possible to modulate continuously electronic properties as the conjugation length and the energy gap.
