Quaternary ammonium intermediates and monomers with liquid crystal properties

Quaternary ammonium intermediates and monomers with liquid crystal properties

Several quaternary ammonium salts, based on ethanolamine and diethanolamine, bearing C 10 and C 12 alkyl chains were synthesized comparatively with the corresponding amides. Smectic-type liquid crystal properties were observed only for the quaternary ammonium salts with either one or two C 12 alkyl...

Zusammenfassung:Several quaternary ammonium salts, based on ethanolamine and diethanolamine, bearing C 10 and C 12 alkyl chains were synthesized comparatively with the corresponding amides. Smectic-type liquid crystal properties were observed only for the quaternary ammonium salts with either one or two C 12 alkyl groups.
