摘　　要：High quality free-standing poly（thiophene-3-acetic acid） （PTAA）, a water-soluble polythiophene derivative, was uccessfully electrosynthesized in boron trifluoride diethyl etherate （BFEE） ＋ 25% （by volume） trifluoroacetic acid （TFA） at 9wer potential （0.38 V versus Pt）. The carboxyl group makes PTAA highly soluble in water, facilitating its potential pplication as a blue-light-emitting material. PTAA films with conductivity of 7 S cm-1 obtained from this medium showed ,etter redox activity and thermal stability. The structure and morphology of the polymer were studied by UV-Vis, FT-IR, H-NMR spectra and scanning electron microscopy, respectively.High quality free-standing poly（thiophene-3-acetic acid） （PTAA）, a water-soluble polythiophene derivative, was uccessfully electrosynthesized in boron trifluoride diethyl etherate （BFEE） ＋ 25% （by volume） trifluoroacetic acid （TFA） at 9wer potential （0.38 V versus Pt）.
