Neutral and doped states of polymers with aromatic rings studied by resonance spectroscopies

摘要

In this work, we present spectroscopic studies on conjugated polymers and oligomers containing phenyl ring, focusing on two families of compounds: PPP and PPV. The resonance Raman Scattering (RRS) technique has been extensively utilized to characterise the neutral of doped states of these compounds but also, we have used high resolution solid state NMR to add information on the nature of the elementary excitations which can appear on these polymers or oligomers in their doped state.
