A simple colorimetric and fluorescent anion chemosensor based on amide moieties, 6-nitro-1,4-dihydroquinoxaline-2,3-dione has been designed, synthesized and characterized by (1)H NMR, ESI-MS and elemental analyses. The strong basic anions such as F(-) and AcO(-) resulted in significant decrease in fluorescent emission intensity of the compound 1, accompanied synchronously with a dramatic color change from colorless to deep yellow in organic medium. (1)H NMR titration experiments shed light on the nature of the interactions between 1 and the anions.
基于酰胺基团的一种简单的比色和荧光阴离子化学传感器，6-硝基-1,4-二氢喹喔啉-2,3-二酮已被设计、合成，并通过核磁共振氢谱（¹H NMR）、电喷雾电离质谱（ESI-MS）和元素分析进行了表征。强碱性阴离子如氟离子（F⁻）和醋酸根离子（AcO⁻）导致化合物1的荧光发射强度显著降低，同时在有机介质中伴随着从无色到深黄色的显著颜色变化。¹H NMR滴定实验揭示了1与阴离子之间相互作用的本质。
