摘要:A New Pyrazole-Based Fluorescent Sensor,5-Amino-3-(5-Phenyl-1H-Pyrrol-2-yl)-1H-Pyrazole-4-Carboxamide (Compound 1),Was Studied For Fluoride Anion (F-) Detection In Organic Or Water-Containing Solution. This Compound Displayed Both Changes In Uv-Vis Absorption And Fluorescence Emission Spectra Upon Addition Of F-. With Increasing Of F-,Blue Emission Intensity Increases Drastically And Reaches Saturation With 607-Fold Enhancement At 424 Nm. The Results Indicate That Compound 1 Has Highly Selectivity For Fluoride Detection Over Other Anions,Such As Cl-,Br-,I-,Hso4-,H2Po4-And Aco-In Dmso Or Aqueous Dmso Solutions. H-1 Nmr Titration And Other Experiments Confirm That The Sensing Process Is Mainly From The Deprotonation Of The Pyrazole-Nh In Compound 1. (C) 2010 Elsevier B.V. All Rights Reserved.
