“…Despite the wide variety of applications of CuAAC, works in which a low catalyst loading is combined with high activity are rare. One of the principles of click-chemistry is the complete avoidance of solvents or the use of a harmless water solvent [13][14][15]. The most common ligand used in CuAAC is tris(benzyltriazolemethyl)amine (TBTA) [16,17].…”

This work focuses on the synthesis of a new series of amphiphilic derivatives of calix[4]arenes for the copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) reaction. The aggregation properties of synthesized calix[4]arenes were studied using various techniques (fluorescence spectroscopy, nanoparticle tracking analysis, and dynamic light scattering). Increasing the length of the alkyl substituent led to stronger hydrophobic interactions, which increased polydispersity in solution. The zwitterionic nature of the synthesized calix[4]arenes was established using different types of dyes (Eosin Y for anionic structures and Rhodamine 6G for cationic structures). The synthesized calix[4]arenes were used as organic stabilizers for CuI. The catalytic efficiency of CuI-calix[4]arene was compared with that of the phase transfer catalyst tetrabutylammonium bromide (TBAB) and the surfactant sodium dodecyl sulfate (SDS). For all calixarenes, the selectivity in the CuAAC reaction was higher than that observed when TBAB and SDS were estimated.

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.
