  Alkali-metal cation recognition induced isomerization of spirobenzopyrans and spironaphthoxazins possessing a crown ring as a recognition site: multifunctional artificial receptors

  摘要：

  Spirobenzopyrans and spironaphthoxazins possessing a monoaza-crown ring were synthesized. Isomerization of these compounds to the open colored merocyanines was induced by recognition of alkali-metal cations and the selectivity of the coloration was found to be governed by several factors: (1) the size of the crown ring, (2) the position of recognition, (3) electric properties of both the complexed cations and the merocyanine dipoles, and (4) the length of the alkyl chains connecting the spirobenzopyran units and the crown units. The spirobenzopyrans represent rationally designed multifunctional artificial receptors for alkali-metal cations.
