Olympiadane is a mechanically-interlocked molecule

Mechanically-interlocked molecular architectures

Mechanically interlocked molecular architectures are connections of molecules not through traditional bonds, but instead as a consequence of their topology. This connection of molecules is analogous to keys on a key chain loop. The keys are not directly connected to the key chain loop but they...

 composed of five interlocking macrocyles that resembles the Olympic rings

Olympic symbols

The Olympic symbols are icons, flags and symbols used by the International Olympic Committee to promote the Olympic Games. Some—such as the flame, fanfare, and theme—are more common during Olympic competition, but others, such as the flag, can be seen throughout the year.-Motto:The Olympic motto is...

. The molecule is a linear pentacatenane or a [5]catenane

Catenane

A catenane is a mechanically-interlocked molecular architecture consisting of two or more interlocked macrocycles. The interlocked rings cannot be separated without breaking the covalent bonds of the macrocycles. Catenane is derived from the Latin catena meaning "chain"...

. It was synthesized and named by Fraser Stoddart and coworkers in 1994. The molecule was designed without any practical use in mind, although other catenanes may have possible application to the construction of a molecular computer.
