title: Synthesis and structure of a vesicular assembly of dialkylammonium-type amphiphile carrying L-3-(3-N-ethylcarbazolyl)alanine.
abstract: A novel unnatural amino acid, L-3-(3-N-ethylcarbazolyl)alanine, was synthesized and used for synthesis of a chiral dialkylammonium-type amphiphile. The synthetic amphiphile formed a vesicular assembly in aqueous dispersion showing gel-liquid crystalline phase transition around 25 °C. The bilayer membrane composed of the amphiphile was nearly free from excimer as evidenced by fluorescence spectroscopy.
