Abstract
Abstract A study of the electrochemistry and electrogenerated chemiluminescence (e.c.l.) of 9,10-dichloro-9,10-dihydro-9,10-diphenylanthracene (DPACl2) in acetonitrile solutions using rotating ring—disk electrode and stationary electrode techniques is described. The measured e.c.l. efficiency was about 0.1 to 0.8%, smaller than that observed for the corresponding DPA radical ion annihilation e.c.l. The emission is independent of applied external magnetic field, supporting the mechanism involving direct formation of emitting singlet. The e.c.l. emission and the electroreduction of DPACl2 depend on the chloride concentration in the solution; the results suggest that this dependence is an electrode surface effect.
