Philic and Phobic Segregation in Liquid-Crystal Ionic Dendrimers: An Enthalpy–Entropy Competition

摘要

A molecular tug of war between non- and semifluorinated alkyl chains (see picture) occurs when they are forced together by ionic attachment to a poly(propylene imine) dendrimer. Unexpected mesomorphic properties appear as a consequence of the competition of both substituents to control the supramolecular organization of the molecules.
