Abstract A set of tris (2-ureidobenzyl) amines 3 was prepared and their dimerization processes thoroughly investigated. In spite of their inherent flexibility, tris (ureas) 3 form dimeric aggregates both in the solid state and in solution. Evidence for the existence of these dimeric species was provided by a combination of techniques (X-ray analysis, NMR and IR spectroscopy, and ESI-MS). The association constants and thermodynamic ...
