recognition motif based on a calix[4]pyrrole macrocycle and tethered carboxylate unit was employed to construct counter cation dependent supramolecularpolymers from low molecularweight A–B type monomers. Reversible pH‐ and thermo‐responsiveness of the supramolecularpolymers were demonstrated for the first time for a calix[4]pyrrole based and anion recognition inducedsupramolecularpolymer.

which was prepared through a condensation reaction of pyrrole and 7‐bromohept‐2‐one. Oligomeric calixpyrrole compounds were found to be capable of extracting tetrabutylammonium chloride and fluoride salts from aqueous media. Extraction abilities of the oligomeric compounds were monitored by NMR and UV/Vis spectroscopy and thermogravimetric analysis.
