This paper reviews the photoinduced reactions of benzodioxinones and how they function in polymer synthesis and UV curing applications. The mechanistic characteristics of the ketene and benzophenone production from the photolysis of benzodioxinone indicate that, under certain conditions, each intermediate may undergo further reactions expedient for the formation of various polymeric structures. While ketenes are efficient contributors to step-growth polymerization when subjected to reaction with the compounds possessing hydroxyl or amine groups, the released benzophenone can be utilized as a photoinitiator in both the free radical and cationic polymerizations. It has been shown that the photolysis of heterobifunctional monomers equipped with benzodioxinone and aliphatic hydroxyl groups leads to the formation of oligoesters with a narrow molecular weight distribution. We also validated the photochemical ability of benzodioxinone to induce the synthesis of block and graft copolymers, hybrid and branched polymers, and cross-linked monofunctional vinyl monomers or hydroxyl group-containing linear polymers.

大分子科学中的苯并二恶酮光化学：进展、挑战和机遇

本文回顾了苯并二恶酮的光致反应以及它们在聚合物合成和紫外线固化应用中的作用。苯并二恶酮光解产生乙烯酮和二苯甲酮的机理特征表明，在某些条件下，每种中间体都可能发生进一步的反应，有利于形成各种聚合物结构。虽然当与具有羟基或胺基的化合物反应时，乙烯酮是逐步增长聚合的有效贡献者，但释放的二苯甲酮可用作自由基和阳离子聚合中的光引发剂。已经表明，具有苯并二恶酮和脂肪族羟基的异双功能单体的光解导致形成具有窄分子量分布的低聚酯。我们还验证了苯并二恶酮诱导嵌段和接枝共聚物、杂化和支化聚合物以及交联单官能乙烯基单体或含羟基线性聚合物合成的光化学能力。
