describe herein the synthesis of new profluorescent nitroxides based on 2,5-disubstituted-1,3,4-oxadiazoles as fluorescent moieties and the 2,2,6,6-tetramethylpiperidine-N-oxyl radical (TEMPO) as paramagnetic probes. The synthesis and optical and electronic properties of the oxadiazole-based precursors of the profluorescent nitroxides, as well as the nitroxides and their reduced forms are also described. Physical
我们在本文中描述了基于2,5-二取代-1,3,4-恶二唑作为荧光部分和2,2,6,6-四甲基哌啶-N-氧基(TEMPO)作为顺磁探针的新的前荧光氮氧化物的合成。还描述了原荧光氮氧化物的基于恶二唑的前体的合成,光学和电子性质,以及氮氧化物及其还原形式。物理研究(即吸收和发射光谱法,循环伏安法)表明,对二唑取代基的发光行为不同。对还原剂的线性响应,即 通过荧光光谱监测的抗坏血酸钠表明,有可能使用合成的化合物作为有效的活性探针来检测各种目标分析物。
