ABSTRACT:
Novel amino substituted bishalomethyl benzene compounds, which are precurs to phenylene polymers are disclosed having non-linear optical properties, and which can be converted to electrically conductive polymers. Such polymers are produced by reacting a novel amino substituted bishalomethyl benzene compound with a dialkyl sulfide to make a bis-cycloalkylene sulfonium salt of 2,5,N,N-tetramethylaniline hydrochloride, which is 2,5-(N,N-dimethyl)aniline hydrochloride dimethylene bis-(tetramethylene sulfonium chloride) and reacting this sulfonium salt 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). The polymers can also be made directly by treatment of the bis chlormethyl dimethyl aminobenzene hydrochloride derivative with alkali metal alkoxide.
