Abstract

We integrate poly(3,4-ethylenedioxythiophene) (PEDOT) into plasmonic nanocavities to systematically study its redox mechanisms via in-situ spectro-electrochemistry. Both dark-field and surface-enhanced Raman scattering (SERS) are tracked during repeated redox cycles for PEDOT thicknesses from 2-20 nm. Surprisingly our data shows systematic changes in these spectra for sub-10nm polymer thicknesses, showing how extreme anisotropies and inverted orientations are produced for conducting polymer chains close to the interface.
