SPECTROSCOPIC ANALYSIS OF STRUCTURE IN POLY(3-BUTYL-CO-3,4-DIBUTYLTHIOPHENE) COPOLYMERS

We have prepared a series of alkyl substituted thiophene copolymers composed of 3-butylthiophene and 3,4-dibutylthiophene units in different percentages. The spectroscopical study of these copolymers performed with NMR techniques combined with optical spectroscopies, such as Raman scattering and UV-Vis absorption is reported.
