Electrically conductive copolymers of pyrrole - obtd. by reacting pyrrole and/or aniline and amino gp. contg. phthalocyanine(s)

摘要

Copolymers or pyrroles contg. inbuilt aniline and/or aminoaromatic cpds. together with units of amino gp.-contg. phthalocyanines. Pref. copolymer contains 10-80 wt.% units of pyrroles and/or aminoaromatic cpd. and 90-20 wt.% units of amino gp.-contg. phthalocyanines. The pyrrole units may be derived from pyrrole itself or substd. pyrroles such as N-alkylpyrroles, N-arylpyrroles, and C-substd. monoalkyl-, dialkyl-, monohalogen-an dihalogen-substd. pyrroles. The aminoaromatic cpd. is esp. aniline or homologues of aniline and the comonomer units from amino gp.-contg. phthalocyanines may be derived from metal-free or metal complexed phthalocyanines. The copolymers may contain intercalcated anions chosen from BF4-, R-SO3-, AsF4-, SbF6-, SbCl6-, PF6-, FeCl4-, ClO4-, HSO4- and SO4(2-) in which R = opt. substd. aromatic or alkylaromatic gp. USE/ADVANTAGE - The copolymers have higher electrical conductivity and improved mechanical properties in comparison to previous electrically conductive polypyrrole systems and are useful e.g. for the prodn. of electrodes, conductors, sensors, electrodes for sec. batteries, as switches, semiconductor components, shielding materials, solar cells and for rendering plastics antistatic.
