The Gluing of a Langmuir−Blodgett Bilayer

Poly(4-styrenesulfonate) has been used to ionically cross-link (glue together) a single Langmuir−Blodgett bilayer derived from an amphiphilic calix[6]arene bearing six hexadecyl and six methylene-trimethylammonium groups. The resulting film is of high quality and robustness, as judged by its He/N2 p...

Zusammenfassung:Poly(4-styrenesulfonate) has been used to ionically cross-link (glue together) a single Langmuir−Blodgett bilayer derived from an amphiphilic calix[6]arene bearing six hexadecyl and six methylene-trimethylammonium groups. The resulting film is of high quality and robustness, as judged by its He/N2 permeation selectivity and by its ability to withstand exposure to chloroform solvent. The creation of a stable organic membrane, having a thickness that is less than 6 nm and a He/N2 permeation selectivity of ca. 305, represents a milestone for LB technology.
