Isophthalamides and 2,6-dicarboxamidopyridines with pendant indole groups: a 'twisted' binding mode for selective fluoride recognition.
Two cleft-like anion receptors have been synthesised that contain indole hydrogen-bond donors and show fluoride selectively in a DMSO-water solution with crystallographic studies showing a 'twisted' binding mode for fluoride in the solid state.
