Used in supramolecular chemistry as a host molecule for molecular recognition due to its rigid pillar-shaped structure and electron-rich cavity. It forms stable inclusion complexes with various guest molecules, especially those with complementary size and polarity, making it useful in sensor development for detecting organic pollutants and biological molecules. Applied in drug delivery systems where it helps encapsulate and release therapeutic agents in a controlled manner. Also employed in the design of smart materials, such as stimuli-responsive hydrogels and molecular switches. Its ability to self-assemble with other components supports its use in constructing nanostructured materials for catalysis and separation technologies.
