A visible light cationic photoinitiating system under chemiluminescence irradiation using sulfonium salt is reported. The visible light emitted from the chemiluminescence reactions, absorbed by the sulfonium salt, essentially leads to the formation of protonic acids capable of initiating cationic polymerization of oxirane and vinyl monomers. The process is suitable for the formation of linear polymer chains as well as cross-linked functional networks with aggregation-induced emission property. Notably, high “post polymerization” efficiency in dark (∼20%) was observed, which can compensate the limited chemiluminescence fluorescence efficiency and favors to increase the conversion.

使用锍盐的化学发光诱导阳离子光聚合

报道了一种使用锍盐在化学发光照射下的可见光阳离子光引发体系。化学发光反应发出的可见光被锍盐吸收，基本上导致形成能够引发环氧乙烷和乙烯基单体阳离子聚合的质子酸。该工艺适用于形成具有聚集诱导发光特性的线性聚合物链以及交联的功能网络。值得注意的是，在黑暗中观察到高“后聚合”效率（~20%），这可以弥补有限的化学发光荧光效率并有利于提高转化率。
