Calix[4]arenes with urea functions attached to the p-positions of the phenolic units usually form dimers in apolar solvents. Tetraureas functionalized by pyridyl and carboxyl groups form dimers only with bis- or tetraloop tetraureas. This heterodimerization was used for the synthesis of a bis-[3]catenane. Tetraureas functionalized with sulfide functions were synthesized for the preparation of monolayers from the dimeric capsules containing electrochemically active guests on gold. Bis-tetraureacalix[4]arenes singly-linked via their wide rim by rigid spacers were synthesized and their self-assembly to polymers in apolar solvents was proved by the 1H NMR spectroscopy and AFM studies.
