Solvophobic interaction promoted supramolecular helical assembly of building blocks of weak intermolecular halogen bonding†
Abstract
We report supramolecular helical assembly in water of β-turn structured bis(N-amidothioureas) containing Br-substitutes of moderate halogen bonding ability, promoted by stronger hydrophobic interaction. The helical polymers show an unusual negative nonlinear CD-ee dependence.
