摘　　要：基于常见的萘酰亚胺荧光团,设计并合成了用于亚硝酸盐专一性识别的荧光探针NOPH。通过核磁氢谱、碳谱和高分辨质谱确证该探针的化学结构。在酸性溶液(pH 1)体系中,探针NOPH能够实现对亚硝酸盐的高效专一性识别,具有较好的抗干扰能力,可以实现裸眼识别效果,检出限为93.6 nmol/L。该探针可以用于高效检测食品中的亚硝酸盐。Based on the common naphthalene fluorophore,a fluorescence probe named NOPH for specific recognition of nitrite was designed and synthesized.The chemical structure of the probe was confirmed by'hydrogen-nuclear magnetic resonance(H NMR),"3carbon-nuclear magnetic resonance("C NMR),and high-resolution mass spectrometry(HR-MS).In the acid solution(pH 1),probe NOPH could achieve efficient and specific recognition of nitrite,with good anti-interference capability and a visible naked-eye detection effect.The detection limit for nitrite was 93.6 nmol/L.The probe can be applied to efficiently detect nitrite in food.
