title: Recognition of alkaline metals and amines by a chromogenic homooxacalix[3]arene receptor.
abstract: [structure: see text] The artificial host molecule 1, consisting of homooxacalix[3]arene and pyridinium N-phenolate dye (Reichardt dye E(T)1) has been prepared. Host 1 contains a proton-ionizable phenol group that acts as a chemical switch to generate color change against alkaline metals and various kind of amines.
