Background
The viscosity is an important index for reflecting the viscosity degree of the solution, mainly depends on the diffusion speed of substances in the solution, has very important application value in the macroscopic and microscopic fields, and plays a crucial role in the whole life system in the viscosity level of the internal environment of the biological system. When the blood plasma viscosity of human body is gradually increased, various diseases, such as hypertension, hyperlipemia, cerebral infarction, heart disease, etc., can be induced, thus endangering the safety of people.
Hydrogen sulfide molecule (H2S) plays a very important role in regulating human physiological functions as one of important signal molecules in the body, and hydrogen sulfide can participate in hemoglobin modification, promote the reduction of nitroso compounds in the body, and regulate the functions of various enzymes in the body. And the hydrogen sulfide molecules in vivo have been shown to be closely related to many serious diseases, such as: hydrogen sulfide molecules can regulate the microvascular circulation in the normal liver and in the liver cirrhosis; and the heart muscle contraction force can be effectively adjusted, the blood vessels can be dilated, and the blood pressure can be stably and bidirectionally adjusted.
Currently, many methods have been developed for detecting viscosity and hydrogen sulfide. However, most detection methods have high cost investment and complicated detection process, and these factors severely restrict the application of some methods in practical detection. Fluorescent probes have become a major detection tool in life and environmental sciences due to their high sensitivity, good selectivity, easy synthesis, low cost, and good biological applications.

However, some fluorescent probe molecules can only detect viscosity or hydrogen sulfide, and can not realize detection of multiple response modes of one probe. Therefore, the simple, efficient and multi-response detection technology has quite important practical significance and application prospect.
