采用脉冲电解停流系统建立了一种新的电致化学发光（ECL）测定方法。用这种方法可以观察到由不同种类自由基离子组成的能量充足和能量不足的化学体系的电致发光。在噻蒽阳离子自由基和芘阴离子自由基的反应中，发现随着前体的加入，发射光谱发生了变化，反映了溶液中复杂的电子和能量传递过程。此外，发射光谱被发现强烈依赖于其他分子存在时，三个物种混合。
New methodology for the measurement of electrogenerated chemiluminescence (ECL) has been developed by using a pulse-electrolysis stopped-flow system. Using this method, the ECL from both energy sufficient and energy deficient chemical systems composed of different kinds of radical ions can be observed. In the reaction between the thianthrene cation radical and the pyrene anion radical, it was found that the emission spectra changed with the addition of the precursors, reflecting both complex electron and energy transfer processes in solution. In addition, the emitted spectrum was found to strongly depend on other molecules present when three species were mixed.
