and their interaction with primary or secondary amines under air and light in organic-aqueous mixtures to give rise to a new class of persistent organic radicals, described on the basis of their electron paramagnetic resonance (EPR), as well as UV–vis, fluorescence, NMR, and quantum mechanics calculations, and their prospective use as multi-signal reporters in a smart label for fish freshness.
我们描述了有机芳基混合物中空气和光照下含氟芳基脲和酰胺的合成以及它们与伯胺或仲胺的相互作用,从而产生了一类新型的持久性有机基团,在其电子顺磁共振(EPR)的基础上进行了描述,以及紫外可见,荧光,核磁共振和量子力学计算,以及它们在鱼类新鲜度智能标签中作为多信号报告物的预期用途。
