AbstractMolecules containing polarized NH fragments that behave as anion-binding motifs are widely used as receptors for recognition and sensing purposes in aprotic solvents. We present here a new example of a receptor, 3-amino-5-(4,5,6,7-tetrahydro-1H-indol-2yl) isoxazole-4-carboxamide (receptor 1), which contains pyrrole, amide and amino subunits. This receptor shows both changes in its UV-vis absorption and fluorescence emission spectra upon the addition of F-, resulting in highly selectivity for fluoride detection over other anions, such as Cl-, Br-, I-, HSO4-, H2PO4 - and AcO- in CH3CN. H-1 NMR titration, time- dependent density functional theory (TDDFT) calculations and other experiments confirm that the sensing process is brought about by deprotonation of the pyrrole-NH in receptor 1.
