Abstract
A comprehensive photophysical and spectroscopic Raman study guided by Density Functional Theory and Hartree-Fock calculations has been done in a series of fully oxidized oligothiophenes with variable chain length, up to four rings. A comparison with the properties of oligoenes and oligothiophenes is proposed.
Keywords: oligothiophenes, p-conjugation, photophysics, Raman spectroscopy, theoretical calculations.
