| Outline of Final Research Achievements |
A 3-hydroxyphenyl-substituted dioxetane fused with a tetrahydrofuran ring thermally decomposes (TD) in apolar solution to give a 3-oxopropyl 3-hydroxybenzoate with the emission [Lmax = 405 nm] due to excited ketone moiety. The dioxetane gave also the keto ester by TD in crystal (TDcryst), though the light emitted was due to excited oxidobenzoate [Lmax = 464 nm] formed by CTID (CT-induced decomposition) mechanism. The unique chemiluminescent TDcryst of the dioxetane was presumably the result of hydrogen bonding (HB) formed in the crystal between a phenolic proton of a dioxetane molecule and a peroxide oxygen of another dioxetane. On the other hand, a 4-benzazolyl-3-hydroxyphenyl substituted dioxetanes underwent TDcryst to effectively give light. Furthermore, photolysis of a crystalline dioxetane bearing a 4-benzimidazolyl-3-hydroxyphenyl group at -78o gave the corresponding keto ester, the stereochemistry of which was apparently different from that of authentic one.
