Tris(ureidobenzyl)amine derivatives 1a,b form dimeric aggregates in apolar solution and in the solid state. Specifically, the meta-substituted tris(urea) 1a is able to transform into supramolecular gels in certain solvents via sonication.

Tris(m-ureidobenzyl)amines dimerize both in solid state and in solution to give molecular capsules which are able to encapsulate small molecules. The self-assembly was confirmed by crystal X-ray analysis and NMR spectroscopy. The X-ray structure showed the encapsulation of one molecule of CH(2)Cl(2). This new type of capsules presents a propeller-like topology and a belt of six hydrogen-bonded ureas
