✦ Synopsis

Poly(2,5-thiophenediyl) (1) was prepared electrochemically from 2,2';5',2"-terthienyl (1) on various metal electrodes (Pt, Au,Ni,Ni sputtered with Au) in acetonitrile, with tetrabutylammonium perchlorate as an electrolyte salt under application of varying temperatures (-5"C, room temperature) and current densities (0.05 to 1 mA/cm*). Coatings with a rough surface structure were formed by higher current densities, whereas low current densities built up a homogeneous, compact and smooth surface structure. Ni electrodes coated with Au formed such smooth surface structures even at higher current densities.

Morphologie von Poly(2,j-thiophendiyl) hergestellt durch Elektropolymerisation von 2,2';5:2"-Terthienyl

Poly(2,5-thiophendiyI) wurde elektrochernisch aus 2,2';5',2"-Terthienyl an verschiedenen Metallelektroden (Pt, Au, Ni, Ni besputtert mit Au) in Acetonitril mit Tetrabutylammoniumperchlorat als Elektrolytsalz bei verschiedenen Temperaturen (-92, Raumtemperatur) und Stromdichten (0,OS bis I mA/cm*) hergestellt. Polymerschichten mit einer rauhen Oberflachenstruktur werden bei hoheren Stromdichten gebildet, wohingegen geringere Stromdichten eine homogene, kompakte,
