Abstract: The photochromism and alkali metal cation-induced coloration of indolinospiropyrans possessing monoaza-benzo-15-C-5 at 8-position were investigated by UV-Vis spectrometry. The results indicated that these compounds show negative photochromic properties differed from those of crowned spiropyran derivatives reported, and have an excellent recognition of alkali metal canon.

Key words: Crown ether, Spriopyran, Nagative photochromism, Alkali metal ion, Recognition ability
