Dye Chemosensing Effect and Characterization Based on Hydroxyl Anthracene and Naphthalene Moiety
In this work, we have studied the detection properties of 1,4-dihydroxyanthracene-9,10-dione (dye 1), 3-hydroxy-2-naphthoic acid (dye 2) and methyl-3-hydroxy-2-naphthoate (dye 3), which were used as dye chemosensors for the metal ion complexing. Metal binding sites in dye 1, 2, and 3 show similar structural characteristics. Ketone, hydroxyl and carboxyl groups provide the functions to bind the metal ions. Metal ion detection properties of these dyes were investigated by UV-Vis absorption, fluorescent emission, HOMO/LUMO energy level and potential and job's method.
