biostudies-literatureUnknown8(7)Zhao ZXA macrocyclic tetra-imidazolium salt (<b>2</b>) based on quinoxaline was prepared and characterized. The recognition of <b>2</b> to nitro compounds was investigated by fluorescence spectroscopy, ¹H NMR titrations, MS, IR spectroscopy, and UV/vis spectroscopy. The results displayed that <b>2</b> was able to effectively differentiate <i>p</i>-dinitrobenzene from other nitro compounds via the fluorescence method.ACS omega6869-6874https://www.ebi.ac.uk/biostudies/studies/S-EPMC9947943biostudies-literaturePreparation of a Tetra-Imidazolium Salt and Sensing for <i>p</i>-Dinitrobenzene.PMC9947943Zhao ZXLiu QXZhao DXWu YYfalsePreparation of a Tetra-Imidazolium Salt and Sensing for <i>p</i>-Dinitrobenzene.A macrocyclic tetra-imidazolium salt (<b>2</b>) based on quinoxaline was prepared and characterized.
