Thermal and Chemiluminescent Property of Dioxetanes Having an N-Arylacridane Structure
摘要:
Novel dioxetanes having an N-arylacridane structure were syn thesized. Studies on thermal stability and chemiluminescent property of these compounds showed that the aryl group cannot stabilize the dioxetane structure so much but can trigger the chemiluminescence by formation of the phenoxy anion.
Thermal and Chemiluminescent Property of Dioxetanes Having an N-Arylacridane Structure
摘要:

Oxirane derivatives having acridane and adamantane structures were designed as a novel chemiluminescent precursor and were found to have a characteristic chemiluminescent ability which is introduced by a two-step trigger reaction involving treatment with alkaline H2O2 and subsequent acidic treatment. Structural study of the oxirane derivatives showed that the CIEEL mechanism is involved in this chemiluminescent reaction and it was also found that the chemiluminescent profile is affected by the kind of acid employed in the trigger reaction.

9-Adamantylidene-10-alkyl-9,10-dihydroacridine oxide as a novel and potential chemiluminescent precursor: Proximity effect of the nitrogen atom
An oxirane derivative having acridane and adamantane moieties was prepared and proved to show potential chemiluminescent property on treatment with alkaline hydroperoxide and subsequently with hydrochloric acid, in which the electron-donating property of the nitrogen was experimentally shown to play an important role for the chemiluminescence.
