Properties of Imidazolinium-containing Multiblock Amphiphile in Lipid Bilayer Membranes

Abstract

A multiblock amphiphile CBA bearing a cationic imidazolinium moiety at its center formed different types of assembly in THF and CHCl₃, which show characteristic emission bands around 300 and 465 nm upon excitation at 295 and 320 nm, respectively. These assemblies were able to be transferred into lipid bilayer membranes, keeping the similar spectral profiles with those in solutions. These results indicate a new potential of self-assembling processes for the control of supramolecular architecture hierarchically formed in lipid bilayer membranes.
