The Effect of "Chemiluminescence Quenching" on the Chemiluminescence Quantum Yields from 9-Benzylacridine and 9-Benzyl-10-methylacridinium Iodide

A visible chemiluminescence (CL) has been found from the air oxidation of 9-benzyl-10-methylacridinium iodide, in contrast to the case of 9-benzylacridine, from which only a feeble CL could be detected.The difference in the CL quantum yields from the acridinium salt and acridine is interpreted in terms of a "CL quenching" of the chemiexcited species by benzaldehyde generated simultaneously in a solvent cage.
