Poly(3,4-ethylenedioxythiophene) (PEDOT) is one of the promising conjugated polymeric materials for organic devices such as organic solar cell or organic electroluminescence display. Hydroxypropyl cellulose (HPC) is a product of chemical-modified cellulose. HPC shows liquid crystal at appropriate condition in solvents. HPC has been used for a binder of medicines and can be applied for green sustainable chemistry in materials science. In this study, poly(bis-(3,4-ethylenedioxythiophene)), abbreviated as poly(bis-EDOT), film is prepared in cholesteric liquid crystals with electrochemical polymerization. We employ a dimer of EDOT (bis-EDOT) as a monomer because bis-EDOT shows good affinity with liquid crystals and the linear shape of bis-EDOT allows pre-orientation in liquid crystal prior to polymerization. The polymer film thus prepared in cholesteric liquid crystals (CLC) shows characteristic circular dichroism (CD) derived from 3-D asymmetric super structure. This study demonstrates that polymerization of the linear-shaped bis-EDOT can effectively imprint 3-D asymmetric structure from HPC as a polymer CLC matrix and form conductive polymer/non-conductive polymer composite.

“…The choice of inorganic and organic components for preparation of these composite materials is based on the excellent stability of the PEDOT layer in aqueous solution and its doped state [35][36][37], and the electrocatalytic activity of PB [38,39], respectively. The PEDOT organic component is in its conducting state in the potential region where the PB inorganic component exhibits its good electrocatalytic activity.…”

Here we have studied the electrocopolymerisation of binary mixtures of functionalised thiophenes in varying compositions and determined independently for each copolymer the spectroelectrochemical responses and the composition of the material using x-ray photoelectron 15 spectroscopy. We have observed strong correlations between the composition of the copolymer material and the composition of the binary solution from which the polymer was grown. In addition, we have shown that the spectroelectrochemical properties of the copolymers indicate the presence of random copolymer material where the λ Max values of the neutral, undoped, polymer scales with composition but also suggest that there may be small amounts of block copolymer or 20 phase-separated mixtures of the homopolymer components.
