The Importance and Use of Energy Transfer in the Liquid-Phase Chemiluminescence

Nonradiative electronic energy transfer (ET) is of great importance and of wide use in studies of chemiluminescence (CL) in solution. Some components of a chemiluminescent system, e. g. reactants, intermediates or products may serve as efficient energy acceptors. In some cases fluorescent energy acceptors, the activators of CL, are necessary components of a CL system. In contrast to the conventional (non-laser) photoexcitation the chemical excitation may produce a triplet state directly, rather than only via the excited singlet state.
