摘要: Abstract A new calix[4]arene derivative in 1,3-alternate conformation bearing four fluorescent 1,3,4-oxadiazole units was synthesized as a chemosensor. This chemosensor displayed highly selective recognition of Cu 2+ among various metal ions by the fluorescence quenching. The binding between and showed 1:2 stoichiometry which investigated means mole ratio method.
