Popis:	Ferrocene- and iron-arene salts can photoinitiate polymerization of pyrrole in the presence of halogenated solvents, such as CH2CH2Cl2, CHCl3, and CCl4, when irradiated with UV light (254 nm). The polypyrroles obtained are black colloidal powders and have low conductivity in the range of 10−5 S cm−1 and rather poor electrochemical properties, which can be the result of loss of conjugation by halogenation. Polypyrrole samples contain both covalently bounded CCl3 groups (from CCl4) and ionic FeCl− 4. A mechanism of photoinitiated polymerization of pyrrole has been proposed.
