Optical Anion Receptors with Urea/Thiourea Subunits on a TentaGel Support

[Image: see text] Two simple chemosensors with urea (L1) and thiourea (L2) groups were synthesized and studied by different spectroscopic techniques. Both receptors can sense acetate (Ac(–)), dihydrogen phosphate (H(2)PO(4)(–)), and fluoride (F(–)) anions, accompanied by changes in UV–vis and (1)H N...

description [Image: see text] Two simple chemosensors with urea (L1) and thiourea (L2) groups were synthesized and studied by different spectroscopic techniques. Both receptors can sense acetate (Ac(–)), dihydrogen phosphate (H(2)PO(4)(–)), and fluoride (F(–)) anions, accompanied by changes in UV–vis and (1)H NMR spectra, and an optical response is observed as a color change of the solutions due to deprotonation and hydrogen-bonding processes. Also, L1 and L2 were supported on TentaGel resins (R1 and R2), and their fluoride-sensing properties in DMSO and water solutions were studied. Interestingly, R2 can sense fluoride ions in sample solutions of 100% water.
