Modulation of Interfacial Properties of Functionalized Calixarenes

Calix[n]arene and their amphiphilic derivatives act as Strong ligands. by selectively binding cations and small organic molecules (such as chloroform. toluene. fullerene). The presence of a cavity and of specific electron donor Sites results in their ability to form stable host-guest systems with electron-acceptor molecules. We report our Studies Oil tile interfacial properties of amphiphilic calixarenes both at the liquid, liquid and at the air liquid interfaces, and their selective complexation of alkaline cations and small organic molecules, by performing, Langmuir isotherms and small-angle neutron scattering experiments. Changing the guest species. the functional groups, and the experimental conditions (such as temperature, concentration, and ionic Strength) call efficiently modulate the interfacial properties of these amphiphilic ligands.
