摘要：

Novel spirobenzopyran derivatives carrying monoazacrown moieties at the 8-position undergo selective complexation of alkali metal ions and thereby isomerization to their corresponding merocyanine form in the dark; the isomerization is enhanced especially by Li+ that is likely to interact with the phenolate anion intramolecularly when bound to the crown rings.
