Abstract

Chromogenic 1,3-calix[4](crown-5 and -6) ethers containing azophenol and indophenol signalling groups were synthesized and their optical recognition toward alkali and alkaline earth metal cations was investigated by UV - visible spectrophotometry. A calcium ion preference was found to be characteristic of most ligands. A calix[4]crown-5 indolo-spiropyran derivative was also prepared to study the photoisomerization equilibrium of the spiropyran - merocyanine system.
