  摘要：

  在过去的二十年中，材料化学领域越来越多的兴趣集中在用作新型磁性材料的有机高自旋分子的合成设计上。基于双（吡唑基）吡啶核的共轭自由基原则上非常有吸引力，因为它们本身在单个分子实体上结合了光学、螯合和磁性。通过具有 Ullman 自由基的双（4'-甲酰基）衍生物对该核心的功能化产生新的功能性双自由基，其可进一步用于超分子结构。在本文中，我们描述了 2,6-bis[4'-(3-oxo-1-oxyl-4,4,5,5-tetramethylimidazolin-2-yl)pyrazol-1'-yl 的合成、结构和性质]吡啶(Pz2PyNN)和2,6-双[4-(1-氧基-4,4,5,5-四甲基咪唑啉-2-基)吡唑基]吡啶(Pz2PyIN)。这两种双自由基可以通过 UV/Vis、IR 和 EPR 光谱清楚地区分。蓝色 Pz2PyNN 的光吸收出现在 λmax= 610 nm (ϵ ≈ 1700 M−1 cm−1)
