  • Patent number: 5604292
    Abstract: Novel conjugated amino substituted phenylene polymers are disclosed having on-linear optical properties, and 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). The polymers can also be made directly by treatment of the bis chlormethyl dimethyl aniline hydrochloride derivative with alkali metal alkoxide.
    Type: Grant
    Filed: May 31, 1994
    Date of Patent: February 18, 1997
    Assignee: The Untied States of America as represented by the Secretary of the Navy
    Inventors: John D. Stenger-Smith, William P. Norris, Andrew P. Chafin, Scott T. Sackinger
  • Patent number: 5578699
    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.
