Crown-ether amphiphiles for the preparation of ion-binding Langmuir-Blodgett films

Two crown-ether amphiphiles bearing a hydrophobic azobenzene tail were prepared to construct ion-binding Langmuir-Blodgett (LB) films. Highly oriented LB films were obtained from the amphiphiles owing to the strong stacking interactions between the adjacent azobenzene moieties, in spite of the limit...

Summary:Two crown-ether amphiphiles bearing a hydrophobic azobenzene tail were prepared to construct ion-binding Langmuir-Blodgett (LB) films. Highly oriented LB films were obtained from the amphiphiles owing to the strong stacking interactions between the adjacent azobenzene moieties, in spite of the limited hydrophilicity of the crown-ether residues. Potentiometric measurements showed that the LB films deposited on a glassy-carbon electrode can bind alkali-metal ions selectively from solution.
