ABSTRACT:
A process for synthesizing novel conjugated amino substituted phenylene pmers is disclosed. The process results in polymers having non-linear optical properties, and the polymers can be converted to electrically conductive polymers. The process involves reacting a novel bis-cycloalkylene sulfonium salt of 2,5,N,N-tetramethylaniline hydrochloride, such as 2,5-(N,N-dimethyl)aniline hydrochloride dimethylene bis-(tetramethylene sulfonium chloride) with alkali metal hydroxide to form a cycloalkylene sulfonium salt precursor polymer, and then heating the precursor polymer under conditions to produce the amino substituted phenylene vinylene polymer, such as poly(2-(N,N-dimethylamino) phenylene vinylene). Another process involves treatment of the bis chlormethyl dimethyl aniline hydrochloride derivative with alkali metal alkoxide.
