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. Cryptophanes can … See more Cryptophanes were discovered by André Collet and Jacqueline Gabard in 1981 when these researchers created, using template-directed synthesis, the first cryptophane, now known as cryptophane-A. See more The anti cryptophane isomer belongs to the D3 point group and the syn cryptophane isomer belongs to the C3h point group. Both molecules therefore do not exhibit a dipole moment. See more Cryptophane cages are formed by two cup-shaped [1.1.1]–orthocyclophane units (see cyclotriveratrylene), connected by three bridges (denoted Y). There are also choices of the peripheral substitutes R1 and R2 attached to the aromatic rings of the units.
