Abstract
The ratio of the intensities of dimer to monomer emission in the spectrum of electrochemiluminescence from solutions of 9,10-dimethylanthracene in dimethylformamide under various conditions has been compared with the ratios observed in the spectra of prompt and delayed fluorescencel. The results indicate that two groups of processes contribute to the electrochemiluminescence. One group leads to direct population of the excited state of the dimer and the other to direct population of the excited state of the monomer. Triplet-triplet annihilation is excluded as a main contributor to electrochemiluminescence except at high temperatures and applied voltages.
