Hydrophobically driven twist sense bias of hollow helical foldamers of aromatic hydrazide polymers in water†
Abstract
Three aryl hydrazide foldamer polymers, which bear different numbers of chiral pentaethylene glycol chains, have been synthesized. Circular dichroism and UV-vis studies reveal that two of them can be driven by hydrophobicity to form helical hollow conformation in water that exhibit strong twist sense bias.
