A new fluorophore pyrido[1,2-]benzimidazole based ratiometric fluorescent probe for the selective detection of sulfite ions in water was investigated. It shows large (pseudo) Stokes shifts (260 nm), high FRET efficiency, high selectivity and sensitivity. A distinct color change from red to colorless was observed and importantly, it proves to be a convenient and efficient tool to detect the sulfite levels in sugar samples.
研究了一种基于新型荧光团吡啶并[1,2 - ]苯并咪唑的比率型荧光探针，用于选择性检测水中的亚硫酸根离子。它具有大的（伪）斯托克斯位移（260 nm）、高荧光共振能量转移效率、高选择性和灵敏度。观察到明显的从红色到无色的颜色变化，重要的是，它被证明是一种方便且高效的检测糖样品中亚硫酸根含量的工具。
