ESR INVESTIGATION OF A NEW LYOTROPIC LAMELLAR PHASE FROM AN AMPHIPHILE WITH A CATIONIC HEAD GROUP.

Article abstract of DOI:10.1080/00268948108073610

A new lamellar lyotropic phase with a positively charged polar interface has been obtained by mixing water and decanol with n-decyl isonicotinate hydrochloride in appropriate concentration. The order parameters of several spin probes incorporated in this mesophase have been determined by electron spin resonance spectroscopy. A comparison is made with the results for the same probes in the lamellar phase of water, decanol, and sodium decanoate, having an anionic interface. The experimental findings are rationalized in terms of selective interactions of the probes with specific regions of the bilayers.
