Abstract
Novel bis-sulfonium salts of amino substituted bis(halomethyl)benzene are disclosed. The sulfonium salts are prepared by reaction of an amino substituted bis(halo methyl)benzene with an aliphatic sulfide. These sulfonium salts can be made into polymer having non-linear optical properties, and polymers which can be converted to electrically conductive polymers. Such polymers are produced by 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).
