A calix[4]pyrrole functionalized with an amidoindole ester for the selective recognition of the dihydrogen phosphate anion
A bisamidoindole ester-functionalized calix[4]pyrrole (2), which features additional hydrogen bond donors and acceptors, complexes dihydrogen phosphate (H<sub>2</sub>PO<sub>4</sub><sup>-</sup>) with high affinity and selectivity. This binding takes place <i>via</i> distinct modes compared to those observed for <i>meso</i>-pyrrolic calix[4]pyrrole 1 and the parent calix[4]pyrrole, underscoring the impact of strategic functionalization on anion binding geometry and selectivity.
