A novel methodology towards fabrication of multilayer organic devices, employing
electrochemical polymer growth to form PEDOT and PEDTT layers, is successfully
demonstrated. Moreover, careful control of the electrochemical conditions allows the
degree of doping to be effectively altered for one of the polymer layers. Raman
spectroscopy confirmed the formation and doped states of the PEDOT/PEDTT bilayer.
The electrochemical deposition of a bilayer containing a de-doped PEDTT layer on top
of doped PEDOT is analogous to a solution-processed organic semiconductor layer
deposited on top of a PEDOT:PSS layer without the acidic PSS polymer. However, the
poor solubility of electrochemically deposited PEDTT (or other electropolymerised
potential candidates) raises the possibility of depositing a subsequent layer via
