M. Dreja et al., CATIONIC AMPHITROPIC GEMINI SURFACTANTS WITH HYDROPHILIC OLIGO(OXYETHYLENE) SPACER CHAINS, Chemical communications, (13), 1998, pp. 1371-1372
New gemini diammonium surfactants have been synthesized in which the s
pacer chain consists of oligo(oxyethylene) units and which exhibit the
rmotropic liquid crystalline lamellar a and beta as well as lyotropic
mesophases.
