Research on supramolecular polymers is in full bloom: the seed was planted 25 years
ago, with the first report on the hydrogen bond-directed self-assembly of liquid crystalline polymers,
and it has now branched out in several directions, each characterized by different recognition
motifs and non-covalent interactions underlying the most diverse families of supramolecular
polymers devised so far. Among these, calixarene-based polymers have been intensively studied,
even though calixarenes have enjoyed much less attention than the smaller homologous
calixarenes. Three strategies have emerged so far for the construction of AABB- and/or ABtype
polymers, namely, C60 encapsulation, primary alkylammonium complexation, and organic cations recognition. This review article
aims at organizing the results obtained (and knowledge gained) to date on the self-assembly of calixarene-derived building blocks.
Keywords: Calixarenas, fullerene, molecular recognition, primary alkylammonium, self-assembly, supramolecular polymers.
