Resorcinarenes are macrocyclic receptors obtained through the condensation resorcinol and aldehydes. The molecular skeleton of resorcinarene allows for their conversion into an amphiphilic structure through a simple chemical reaction. Interesting examples of amphiphilic macrocycles (16–17) for self-assembly were synthesized by Tanaka et al. (Tanaka et al. 1999). The intermolecular and intramolecular H-bonds between the OH group played a vital role in stabilizing the assembled vesicles. A particle size distribution between 30 to 240 nm was confirmed by the DLS measurement, where the population of the 53 nm particles was maximum.

Calix[4]resorcinarene[19,20] is a type of macrocyclic compound, which can be used as a ligand for the separation and determination of metal ions. The unique structure of calix[4]resorcinarene allows it to selectively bind to specific metal ions, making it a useful tool in analytical chemistry. The introduction of hydroxamic acid groups into the calix[4]resorcinarene structure can further enhance its selectivity and sensitivity for certain metal ions, including rare earth elements. This allows for more precise and accurate analysis of these elements in a sample. Additionally, the calix[4]resorcinarene ligand can be used in liquid-liquid extraction techniques, which can be a faster and simpler method of separation and determination compared to other techniques.
