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 ...
