| Abstract: | High quality free-standing poly(thiophene-3-acetic acid)(PTAA),a water-soluble polythiophene derivative,was successfully electrosynthesized in boron trifluoride diethyl etherate(BFEE)+ 25%(by volume)trifluoroacetic acid(TFA)at lower potential(0.38 V versus Pt).The carboxyl group makes PTAA highly soluble in water,facilitating its potential application as a blue-light-emitting material.PTAA films with conductivity of 7 S cm"1 obtained from this medium showed better redox activity and thermal stability.The structure and morphology of the polymer were studied by UV-Vis,FT-IR, ~1H-NMR spectra and scanning electron microscopy,respectively. |
