Abstract

Design of supramolecular systems enabling a fluorimetric detection of chemical species in solution has attracted much attention. 1 Much effort has been made toward development of a fluorescent pH sensor (H + detection). 2 The simplest pH sensing system consists of a fluorophore (eg, anthracene) covalently linked to a polyamine. 3 In this system, the fluorescence intensity (I F ) of the fluorophore decreases with an increase in pH of the solution. This occurs because ...
