摘要: This work presents the synthesis and characterization of L2 L3, which formed with previously described ligand L1 a family three tris(tetraamine) ligands based on mesitylenyl spacer. The trimeric differ from one to other by nature their tetraamine moieties: triethylenetetraamine (L1), cyclen (L2), constrained (L3). impact rigidification structure L3 acid―base properties is investigated, behavior towards triphosphate (TriP), adenosine monophosphate (AMP), diphosphate (ADP), (ATP) anion receptors explored potentiometric investigations. To characterize understand driving forces implicated in supramolecular assemblies, results are supported 1 H 31 P NMR measurements performed over wide pH range. ATP appears as most complexed particular attention given comparison its inorganic analogue highlight contribution π-stacking interactions. Results unambiguously show various coordination scheme induced ligands.
