Used primarily in coordination chemistry, this compound acts as a selective host for alkali metal ions, particularly sodium and potassium. Its crown ether-like structure enables it to form stable complexes with these ions, making it valuable in ion transport studies and membrane technologies. It is also employed in the development of sensors for detecting specific metal ions in analytical chemistry. Additionally, its unique sila-crown structure is explored in supramolecular chemistry for creating novel molecular assemblies and functional materials.
