Abstract
Host–guest complexation with cucurbit[7]uril of anthocyanin model compounds in which acid–base equilibria are blocked resulted in essentially complete stabilization of their color. The color protection is a thermodynamic effect and establishes a strategy to stabilize these colored compounds at pH values of interest for practical applications.
