The electrogenerated chemiluminescence of intramolecular donor-acceptor compounds was studied in several organic solvents using the triple-step method. The compounds studied were aryl derivatives of N, N-dimethylaniline and 9-anthryl derivatives of aromatic amines. In the electrogenerated emission spectra only the twisted intramolecular charge-transfer (TICT) band was observed. The Feldberg plot analysis indicates that the emitting species are formed directly by the electron transfer between electrogenerated radical cation and radical anion (singlet route). High emission efficiences (φ ECL up to 0.05) as well as high yields of the emissive excited state (φ ES up to 0.21) have been found. The φ ES values obtained have been interpreted in terms of the Marcus theory, taking into account both static and dynamic dielectric properties of the solvent as well as both electronic and vibrational excitation of the reaction products. The main reaction channels are the adiabatic formation of excited TICT state (controlled by the solvent dynamics) and the non-adiabatic formation of the local excited triplets.
