Several new nitrilotriacetic acid (NTA) based C₃-symmetric tripodal amides have been synthesized. The NTA branches are alkyl chains or esters derived from amino acids of different length, namely glycine, β-alanine and γ-aminobutyric acid. The behavior of these compounds to entrap different monoanions has been tested revealing that they are good ligands able to form host-guest complexes with the following affinity order: H₂PO₄^– > CH₃CO₂^– > PhCO₂^– > Cl^–, in DMSO.
