Supramolecular tapes formed by a catanionic cyclodextrin in water
Abstract
A β-cyclodextrin substituted with amino and carboxymethyl groups on the primary and secondary side respectively, has a positively charged primary face and a negatively charged secondary face at neutral pH, and self-assembles in water into supramolecular tapes that are 50–300 nanometres wide and up to 20 micrometres long.
