Polymerization of pyrrole by cationic photoinitiators

A new method of polymerization of pyrrole in the presence of cationic photoinitiators such as iron-arene salts (ða-C 5H 5)Fe(ða-arene) under visible or ultraviolet irradiation has been described. The synthesized polypyrroles have low conductivity in the range of 10 −5 S cm −1 and rather poor electro...

Description
Summary:A new method of polymerization of pyrrole in the presence of cationic photoinitiators such as iron-arene salts (ða-C 5H 5)Fe(ða-arene) under visible or ultraviolet irradiation has been described. The synthesized polypyrroles have low conductivity in the range of 10 −5 S cm −1 and rather poor electrochemical properties. The polymerization reaction occurs only in the presence of oxygen and is inhibited by the addition of 1,10-phenanthroline. It is initiated by the Fe( iii) species formed by the oxidation of Fe( ii) fragments formed during the photolysis of the photoinitiators used.
