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. (AU)
