Conjugated polymers: a hyper-Rayleigh scattering study

Conjugated polymers have been extensively studied and are implemented in devices such as transistors and lightemitting devices. We will present a solution-based study by linear and nonlinear optical characterization techniques in which we study the behavior of different substituted poly(thiophene)s. A profound hyper-Rayleigh scattering study has been performed in their neutral and oxidized oxidation state while continuously monitoring the transition.
