Abstract:

The objective of this research program was the discovery of bright chemiluminescent reactions suitable for development into illumination and marking devices for field use. Over 175 organic compounds were investigated in the DMSOt-BuOKO2 system in a general screening program. It is concluded from the data that chemiluminescence is a very general phenomenon. Almost every compound studied gave at least weak emission. The indoles were the most promising class of compounds studied. An investigation of 56 indole derivative showed numerous explainable substituent effects. Skatole 3-methylindole fulfills these conditions and was found to be the brightest system studied. The chemiluminescent emitter in the skatole system was unambiguously identified as the excited singlet state of the anion of orthoformamidoacetophenone FAP. The agreement between the chemiluminescence spectrum of the skatole system, and the fluorescence emission spectrum of FAP is among the best to be found for any known system. The emitter in the 2,3-dimethylindole system was shown to have a structure analogous to FAP.
