N,N-Bis-(8-hydroxy-5-nitroquinolin-7-ylmethyl)diaza-18-crown-6, a Chemosensor for Mercury Ions
Abstract
Diaza-18-crown-6 appended with two 8-hydroxy-5-nitroquinoline groups acts as an effective fluorescent chemosensor for Hg(2+). The apparent PK(a)s of the phenolic protons on the ligand decrease significantly in the presence of mercury allowing formation of a neutral, fluorescent complex. The ligand responds selectively to Hg(2+) in the presence of other metal ions including alkali metal and alkaline earth cations, Zn(2+), Cd(2+), Ni(2+) and Cu(2+).
