Keywords: bilayer; electropolymerisation; PEDOT; PEDTT; Raman; Findings Fabrication of multilayer organic electronic devices has been extensively researched in the past 20 years, resulting in numerous processes and

• their ease of electropolymerisation, excellent film-forming properties and because of their likely compatibility with each other [11]. First, PEDOT was deposited on an ITO glass slide by electropolymerisation of EDOT, using a Pt gauze counter electrode and a Ag wire quasi-reference electrode, with

• cycling between 0 V and +1.4 V over 150 cycles sufficient to achieve good polymer growth. Under similar conditions, the PEDOT/PEDTT bilayer was achieved using EDTT and cycling over the range +0.3 V to +1.78 V over 150 cycles (see Figure S1 in Supporting Information File 1 for the electropolymerisation of

• materials being greatly affected by film morphology. The electropolymerisation technique creates a simple test for the viability of a certain structural motif in the PT chain and is considered both as a potential route for the synthesis of a new functional CP and also as a method for the modification of an

• -electrochemical investigation of the polymer film is straightforward; 4) it provides control over the morphology through the choice of solvent, electrolyte and/or the method of electrodeposition. TTF has been incorporated into a CP backbone by electropolymerisation of its bis(EDOT) derivative to afford polymer 2

• . The first example of the electrochemical preparation of PT with a pendant TTF-carboxylic unit (3) was reported by the Bryce group [46] (Scheme 2). The mixture of CH2Cl2 with PhNO2, to supress the electrochemical activity of TTF during electropolymerisation, was used as a solvent. Another example of a
