Benzo-15-crown-5 and dipicolylamine are contained as the binding sites in a ditopic azoprobe (15C5-Azo-n-dpa). However, the selectivities of guest-induced supramolecular chirality for cations and anions were dramatically altered by a slight change in the spacer length of (15C5-Azo-n-dpa)2-γ-CyD complexes in water.

Novel photosignal transduction systems of benzo-15-crown-5 (B15C5) azoprobe/γ-cyclodextrin (γ-CyD) complexes were designed. Four B15C5 azoprobes were synthesized by azo coupling of 4'-aminobenzo-15-crown-5 with phenol (for 15C5-Az-Ph) and N,N-dialkylanili

Crown ether dyes were synthesized in order to develop photometric reagents which are highly selective to alkali and alkaline earth metals. They contain dissociable protons attached to the chromophores of crown ether molecule. Their extraction behavior for alkali and alkaline earth metal ions as neutral complex was examined. The dyes extract potassium and alkalin earth metals, respectively. Dyes with picrylamino chromosphore are effective for extractive photometric determination of potassium. A molecular design of colorimetric reagents is discussed on the basis of crown ethers.
