The syntheses of two rigid organic molecular rods bearing a nitronyl-nitroxide radical and a terminal nitrogen-based functionality like a pyridine or a cyano group are reported. Both new paramagnetic molecules are fully characterized, including crystal structure analysis. Furthermore their magnetic behaviours in the crystalline state are investigated and their spin concentration corroborate their excellent
报道了两个带有硝酰基-硝基氧自由基和末端氮基官能团(如吡啶或氰基)的刚性有机分子棒的合成。两种新的顺磁性分子都具有完整的特征,包括晶体结构分析。此外,研究了它们在结晶状态下的磁行为,并且它们的自旋浓度证实了其优异的纯度。尽管吡啶官能化的棒是通过将相应的苯甲醛转化为苯基-亚硝酰基-硝基氧自由基来合成的,但氰基官能化的棒的合成却证明了通过与间-碘-苯基的交叉偶联反应,可以实现高度复杂的自旋标记分子的可及性。-亚硝酰基-亚硝基氧化物部分。
