DIRECT OBSERVATION OF A RADICAL-ION INTERMEDIATE IN THE CHEMIEXCITATION STEP OF PEROXYOXALATE CHEMILUMINESCENCE

摘要

The chemically initiated electron exchange luminescence (CIEEL) mechanism was proposed by Schuster in the late 1970's and represents the most general explanation for efficient bio- and chemiluminescence phenomena. It consists in a combination of the triplet chemiexcitation, observed in unimolecular decomposition or rearrangement of high-energy compounds (e.g. organic peroxides and hydroperoxides), and electrochemiluminescence, the light emission observed by annihilation of radical-ions generated electrochemically.
