WebThe present invention relates to the cryptophane derivatives of formula (I) capable of encapsulating small molecules such as noble gases for biological and environmental use. In particular, the invention relates to cryptophane derivatives with high affinity for xenon, which can be used as biosensors in clinical imaging. Cryptophanes are a class of organic supramolecular compounds studied and synthesized primarily for molecular encapsulation and recognition. One possible noteworthy application of cryptophanes is encapsulation and storage of hydrogen gas for potential use in fuel cell automobiles.
