Electrogenerated chemiluminescence (eel) of several polycyclic aromatic hydrocarbons (PAH) (‐)/triphenylamine (TPA) derivative (+) mixed systems has been studied at a platinum wire electrode in acetonitrile (ACN) and tetrahydrofuran (THF) solutions using tetra‐ n ‐butylammonium perchlorate (TBAP) as a supporting electrolyte, and the results are reported. Exciplexes, as well as the lowest singlet excited state of PAH, are identified as emitting species in these eel systems. The results shown by the temperature and pulse duration dependencies on eel intensities indicate that exciplexes are formed directly from solvent separated ion pairs. The interaction of PAH in their excited states with several donor molecules is discussed based on eel and fluorescence quenching results.
