Bifunctional fluorescent probe for detecting viscosity and sulfur dioxide

The invention discloses a bifunctional fluorescent probe for detecting viscosity and sulfur dioxide. The red fluorescence of the fluorescent probe is gradually enhanced along with the increase of viscosity, and the blue fluorescence of the fluorescent probe is enhanced along with the increase of SO2, so that different fluorescence response signals are displayed, and the distinguishing detection isrealized. The fluorescent probe provided by the invention has important application value in the field of biochemistry. 本发明公开了一种检测粘度和二氧化硫双功能的荧光探针。该荧光探针随粘度的增加红色荧光逐渐增强，随SO的增加蓝色荧光增强，显示出不同的荧光响应信号，从而实现区别检测。本发明的荧光探针在生物化学领域具有重要的应用价值。
