Synthesis and Characterization of a Novel Fluorescent Molecule Based on Phenanthrimidazole Derivatives
This work describes the design and synthesis of AT-DPIT,a new fluorescent sensing material with stiff anthracene rings and twisted triphenylamine.The properties of AT-DPIT were systematically investigated using UV absorption and fluorescence spectroscopy.Due to the exceptional proton binding ability of the nitrogen atoms on its imidazole ring,AT-DPIT exhibits notable acidochromic properties.With the addition of acid,the fluorescent color of the AT-DPIT solution gradually bursts from the initial bright yellow to colorless.Furthermore,the CH3CN solutions of AT-DPIT demonstrate high selectivity,high sensitivity,and anti-interference for Cu2+detection,enabling a limit of detection for Cu2+at 1.62×10-7 mol·L-1.Consequently,these potential luminophores were synthesized as convenient and promising multifunctional sensors.
