A Non-Aqueous Lyotropic Liquid Crystal with a Starburst Dendrimer as a Solvent

Abstract
A lamellar liquid crystal was formed by octanoic acid and a starburst polyethyleneimine dendrimer of the third generation: The minimum acid content corresponded to an acid/dendrimer molecular ratio of 13, e.g. approximately one acid per amino group. Infrared spectroscopy showed the acid molecules ionized. The maximum number of acids was approximately 2.5 per amino group and now the infrared spectra showed approximately one half of the carboxylic groups to be ionized.
