Abstract

The electro-click reaction of azide-functionalized poly(3,4-ethylenedioxythiophene) (PEDOT-N3) and a terminal alkyne was investigated using electrogenerated Cu(I) species on a bipolar electrode in a gradient manner. The introduction of a perfluoroalkyl group derived from the alkyne moiety onto the PEDOT surface only at the cathodic part of the bipolar electrode was successfully characterized by X-ray analyses and the surface properties of the modified film were studied. The spectroscopic analysis of the rhodamine-functionalized PEDOT prepared similarly in a gradient manner was also performed with a UV-vis spectrophotometer.
