Used in drug delivery systems due to its ability to form stable host-guest complexes with various pharmaceutical compounds, enhancing solubility and stability of drugs. Applied in sensing technologies for detecting small molecules and ions through selective binding. Utilized in environmental chemistry for the removal of pollutants and organic contaminants from water. Explored in catalysis as a supramolecular scaffold to control reaction selectivity. Investigated for use in molecular machines and smart materials due to its rigid structure and reversible binding properties.
