A very generous donor: The electrochemiluminescence (ECL) efficiency and radical stability of pyrene, a poor ECL luminophore, are markedly improved as the number of peripheral multidonor units increased in a series of compounds (see picture). Photophysical and electrochemical studies and theoretical calculations have contributed to the understanding of the ECL enhancement, which is a step forward in the development of new light-emitting materials.
芘是一种较差的电化学发光（ECL）发光体，在一系列化合物中，随着外围多供体单元数量的增加，芘的ECL效率和自由基稳定性显著提高（见图）。光物理和电化学研究以及理论计算有助于理解ECL增强现象，这是新型发光材料开发中的一大进步。
