Electropolymerization of phenylacetylene in acetonitrile

Abstract

The electrooxidation of phenylacetylene (PA) in acetonitrile (0.1 M in LiClO 4 ) produced poly(phenylacetylene). The product was isolated, purified, and characterized. Spectroscopic data showed the trans structure of the polymer. A radical reaction mechanism was proposed in which the oxidation of PA led to the formation of a PA radical in solution, which initiated a radical polymerization. The theoretical treatment for the radical mechanism yielded a reaction rate equation identical to the experimental one. The average molar mass was determined by gel permeation chromatography to be approximately 3100. #

Photophysical Properties and Electropolymerization of Gold Complexes of 3,3′′-Diethynyl-2,2′:5′,2′′-terthiophene

“…This behavior is characteristic of the electropolymerization of a conductive polymer on the working electrode. Both acetylene and thiophene are known to electropolymerize and have similar oxidation potentials, , so it is difficult to predict the structure of the electropolymerized A 2 T 3 .…”
