Calix[4]arene

CAS: 74568-07-3

Calix[4]arenes are a group of aromatic compounds that can be used as optical sensors. They are characterized by the presence of four phenyl rings and an open cavity that is accessible to solvent molecules. The calix[4]arene molecule has two free electron pairs, which makes it possible for the molecule to form stable complexes with various test samples, such as hydrochloric acid, ammonia, and nitric acid. Calix[4]arenes also have linear calibration curves that can be used to measure concentrations of test samples. When heated in the presence of oxygen and water, calix[4]arenes will emit light at a wavelength between 500-600 nm. This light emission is due to an intramolecular hydrogen bond that is formed from the nitrogen atom on one ring to the oxygen atom on another ring.
Calix[4]arenes are also capable of transferring electrons from one ring to another through steric interactions. This process leads to light
