1,2-dioxetane

The chemical substance 1,2-dioxetane is an heterocyclic organic compound with formula C2O2H4, containing a ring of two adjacent oxygen atoms and two adjacent carbon atoms. It is therefore an organic peroxide, and can be viewed as a dimer of formaldehyde. In the 1960s, biochemists discovered that some derivatives of 1,2-dioxetane have a fleeting existence as intermediates in the reactions responsible for the bioluminescence in fireflies, glow-worms and other luminescent creatures. The hypothesis could not be proved because these four-membered cyclic peroxides are quite unstable. Then in 1968 the first example of a stable dioxetane derivative was made at the University of Alberta in Edmonton: 3,3,4-trimethyl-1,2-dioxetane, prepared as a yellow solution in benzene. When heated to 333 K, it decomposed smoothly to acetone and acetaldehyde with the emission of pale blue light. The second example of a dioxetane derivative was made shortly after: the symmetrical compound 3,3,4,4-tetramethyl-1,2-dioxetane, obtained as pale yellow crystals that sublimed even when kept in the refrigerator. Benzene solutions of this compound also decomposed smoothly with the emission of blue light. By adding compounds that normally fluoresce in UV light the colour of the emitted light could be altered.
