Synthesis of a new generation of amphiphiles with multi-cryptand headgroups: A comparative study at air-water interface

Abstract

A laterally non-symmetric aza cryptand has been derivatized with two hydrophobic chains to afford amphiphiles with one cryptand headgroup and two hydrophobic tails. Three such units readily attach to 1,3,5-benzenetricarbonyl trichloride, to form a new generation of amphiphilic molecules with three cryptand headgroups and six hydrophobic chains. These molecules are studied at the air-water interface in a Langmuir trough. They readily form LB-films on a number of substrates that are characterized. © Indian Academy of Sciences.
