A lower rim triazole linked calix[4]arene conjugate as a fluorescence switch on sensor for Zn2+ in blood serum milieu

Abstract

A fluorescence turn-on receptor based on triazole linked calix[4]arene (L) for selective recognition of Zn(2+) in aqueous-methanolic HEPES buffer has been developed and showed its utility for sensing Zn(2+) in blood serum milieu.
