本文介绍了一种光催化剂(三(2-苯基吡啶)Ir[Ir(Ppy)(3)])的用途，该催化剂既能产生自由基又能产生阳离子来引发自由基聚合和开环聚合。值得注意的是，在弱照射(荧光灯、太阳光)下，可以获得良好的阳离子聚合轮廓和最终转化率。通过ESR实验对相关机理进行了研究。
The use of a photocatalyst (tris(2-phenylpyridine)iridium [Ir(ppy)(3)]) being able to generate both radicals and cations to initiate free radical polymerization and ring opening polymerization is presented. Remarkably, under soft irradiations (fluorescence bulb, sunlight), excellent cationic polymerization profiles and final conversions are obtained. The involved mechanisms are investigated by ESR experiments.
