Thiourea-functionalized Tröger’s base receptors 1 and 2 have been synthesized and evaluated as novel for the recognition of anions. Receptor 2 gave rise to significant changes in the absorption spectrum upon titration with AcO and H2PO4 and acted as a colorimetric sensor for F, the interaction of which was also evaluated using 1H NMR spectroscopy.
