Abstract Photo-Fries rearrangements of 4-dodecylphenyl phenylacetate have been investigated in polyethylene films with 0–71% crystallinity and in hexane over a range of temperatures. The results are compared to those reported previously from phenyl phenylacetate and 1-naphthyl tetradecanoate to assess the influence of a long alkyl chain on the in-cage motions of the intermediate singlet radical pairs
摘要 4-十二烷基苯基乙酸酯的 Photo-Fries 重排已在 0-71% 结晶度的聚乙烯薄膜和己烷中在一定温度范围内进行了研究。将结果与先前报道的苯基乙酸酯和 1-萘基十四烷酸酯进行比较,以评估长烷基链对中间单线态自由基对的笼内运动的影响。结果表明,可以通过明智地放置长链取代基和选择特定的聚乙烯类型作为反应基质来调节紧密单线态自由基对的反应性和选择性。
