Abstract

A macroion, having anisotropic surface charge density distribution, shows unique self-assembly behaviour in polar solvents. Regular "blackberry"-like assemblies form in methanol-water mixtures due to counter-ion mediated attraction and the strong contribution of hydrogen bonding. However, rod-like assemblies form in acetone-water mixtures as the charge inhomogeneity effect overcomes the non-directional hydrogen bonding.
