MONOLAYER AND MULTILAYER FILMS OF CYCLODEXTRINS SUBSTITUTED WITH 2 AND 3 ALKYL CHAINS

An investigation is reported on the behavior of amphiphilic cyclodextr ins at the air/water interface. Stable surface pressure vs area curves were recorded for many of the materials investigated. The addition of N(CH3)(4)Cl or KCl to the subphase was found to result in a small but reproducible contraction in the isotherms. Preliminary work also show ed that Langmuir-Blodgett films of some materials could be built up on solid surfaces, although the resulting layers were of poor quality.
