研究了 BODIPY-Le，一种基于硼二吡咯亚甲基的比色和比率荧光探针，用于选择性检测亚硫酸根离子。硼二吡咯亚甲基乙酰丙酯 (BODIPY-Le) 由吲哚基 BODIPY 染料和乙酰丙酰保护基组成，可以通过亚硫酸盐轻松、选择性地脱保护。结果，吸收和发射光谱显示出显着的红移，并且可以实现比色和比率荧光亚硫酸盐探针的开发。此外，BODIPY-Le 还分别在 510 nm 和 620 nm 激发后对亚硫酸根离子表现出显着的开启或关闭型荧光信号传导。
BODIPY-Le, a colorimetric and ratiometric fluorescent probe based on boron-dipyrromethene for selective detection sulfite ion, was investigated. Boron-dipyrromethene levulinyl ester (BODIPY-Le) is composed of an indole-based BODIPY dye and the levulinyl protective group, which could be easily and selectively deprotected by sulfites. As a result, the absorption and emission spectra show a dramatic red shift, and the development of a colorimetric and ratiometric fluorescent sulfite probe could be achieved. Besides, BODIPY-Le also exhibited prominent turn-on or turn-off type fluorogenic signaling toward sulfite ions once excited at 510 and 620 nm, respectively.
