“…However, owing to the intrinsically saline nature of the monomers used, the growth of these aggregates was found to depend on the strength of the ion-pairing effect between the ammonium monomer (formed upon acid treatment) and its counterion. In the course of subsequent studies, to facilitate the acid-promoted head-to-tail self-assembly of this monomer, we have covalently added an ancillary anion-binding site (i.e., an ureido moiety − ) at its upper rim ( UC5-NH 2 ; see Scheme ) …”

A light scattering study shows that the HCl-promoted self-assembly of an amino-calix[5]arene monomer precursor UC5-NH(2), bearing an ancillary ureido binding site, efficiently yields supramolecular polymers with a concentration-independent average mass. These polymers adopt a random-coil conformation and interact among themselves via the adhesive hard sphere pair potential. The findings also indicate the formation of polymer clusters, coexisting in low concentration with the polymers and resulting from the adhesive interpolymer interactions. Unlike polymers, the size of these clusters depends on the monomer concentration.

Dedicated to Prof. Mario Gattuso on the occasion of his retirementModulation and control of the molecular features of a given receptor/substrate, and hence their supramolecular properties, by means of external, nondestructive, stimuli is still a topic of current and increasing interest, not only from a fundamental perspective but also from that of future nanodevices.[1] Light is the most appealing on/off trigger. The combination of its ready availability and easy manipulation, together with the fast rate of photochemical reactions, makes photoregulated systems particularly suited for multifaceted applications in different fields, which range from molecular optoelectronics [2] and energy conversion, [3] to the environment [4] and biomedicine.

A small library of polytopic receptors has been synthesized from meso-p- and meso-m-aminophenylcalix[4]pyrroles and p- or m-phthaloyl or trimesic chloride. Selected bis-carboxylates and the citrate anion, which either exhibit altered distribution profiles in cancerous tissues in comparison with healthy tissues or are metabolites of carcinogenic substances (for example, trans,trans-muconic acid from benzene exposure in humans) were tested as ligands. Varied affinities and binding modes were observed as a function of the number of calix[4]pyrroles and the topology of amide units present in each of the polytopic receptors. The structures of the 1:1 complexes derived by molecular modeling are in excellent agreement with the results of (1)H NMR complexation studies.
