Alkali Metal Sensing with a Fluorescent 5,11,17,23-Tetraphenylcalixarene and the Mechanism of the Fluorescence Change

Article abstract of DOI:10.1246/cl.1994.2431

The fluorescence intensity of a tetraester derivative of the title compound increases markedly upon the N⁺-binding.Hence, this is useful as a new, convenient Na⁺-sensing system.The mechanism of the fluorescence increase is discussed by comparing the fluorescence properties of several reference compounds.
