制备了核黄素四甲基丙烯酸酯（RFlTMA）作为黄素单体，并在聚合诱导相分离条件下与乙二醇二甲基丙烯酸酯（EGDMA）进行共聚。所得的含黄素的介孔网络聚合物，聚（RFITMA-co-EGDMA），被认为是一个更有效的催化剂比核黄素四乙酸酯（RFlTA），一种可溶性的类似物，尽管其异质性，烯烃的有氧加氢，这允许其多次回收和再利用，通过简单的过滤和洗涤，而不损失催化活性。此外，聚合物黄素也被证明是一种有效的光催化剂在苯甲醇的氧化。(C)2020爱思唯尔有限公司版权所有。
Riboflavin tetramethacrylate (RFlTMA) was prepared as a flavin monomer and copolymerized with ethylene glycol dimethacrylate (EGDMA) under polymerization-induced phase separation conditions. The resulting flavin-containing mesoporous network polymer, poly(RFlTMA-co-EGDMA), was found to be a more effective catalyst than riboflavin tetraacetate (RFlTA), a soluble analogue, for aerobic hydrogenation of olefins despite its heterogeneity, which allowed for its multiple recovery and reuse through simple filtrations and washings without loss in catalytic activity. In addition, the polymeric flavin was demonstrated to be utilized also as an effective photocatalyst in the oxidation of benzyl alcohols. (C) 2020 Elsevier Ltd. All rights reserved.
