“…Calix [6]arenes [1] are synthetic macrocycles whose use in supramolecular chemistry finds numerous applications, including the synthesis of sensors, [2] stimuli-responsive devices, [3,4] and catalysts. [5,6] With respect to other cavitands, calix [6]arenes are synthetically flexible and non-palindromic. These features have been exploited, for example, for the synthesis of heteroditopic calix [6](thio)urea macrocycles, which are able to work as receptors and transporters for organic ion pairs.…”

Heteroditopic calix[6]arenes are widely employed macrocycles for the synthesis of pseudo‐oriented interlocked systems and stimuli‐induced molecular machines, among others. Herein, we introduce a new calix[6]arene receptor functionalised with three phenylselenoureido groups. These hydrogen‐bonding donor moieties are able to promote the threading of viologen‐based organic axles inside the macrocyclic cavity to form a stable pseudorotaxane species. Preliminary investigations using 1H‐NMR measurements and semi‐empirical and DFT studies suggested its further use as a platform for the synthesis of rotaxanes.

Supermolecule refers to two or more molecules that are bonded together by secondary bonds between molecules to form a multimolecular system at the level of more than molecules. At this point, the molecules form an orderly aggregation, showing its unique structure and function. Supramolecular catalysts can form structures with specific functions through non‐covalent interactions (e. g., hydrogen bonding, π‐π stacking, etc.) to mimic the catalytic mechanism of natural enzymes and achieve susceptible and specific detection of biomolecules. The application of supramolecules is mainly focused on the self‐assembly of components for the construction of sensing platform. Therefore, supramolecular catalysts have a huge potential in biomolecule detection. This article focuses on the application of cyclodextrins(CD), cucurbit[n]uril(CB), porphyrins(PP) and Calix[n]arenes(CA) in the field of catalysis and in improving detection sensitivity. Research progress of supramolecular catalysts in polymerization amplification is summarized in this paper.
