Viscosity and polarity response type platform fluorescent probe, hydrogen sulfide detection fluorescent probe as well as synthesis process and application of viscosity and polarity response type platform fluorescent probe and hydrogen sulfide detection fluorescent probe

The invention discloses a viscosity and polarity response type platform fluorescent probe, a hydrogen sulfide detection fluorescent probe and a synthesis process and application thereof. The structure of the hydrogen sulfide detection fluorescent probe is shown in the specification, . Aiming at the problems of poor operability, low sensitivity and the like in polarity and viscosity detection in a physiological microenvironment, the invention provides a high-sensitivity platform fluorescent probe which can be used for detecting environmental viscosity and polarity, and the probe can reflect the change of environmental viscosity through the dramatic change of fluorescence intensity, so that the sensitivity of the environmental viscosity is improved. The change of environment polarity is reflected through the change of a fluorescence emission position; meanwhile, the probe molecule can be used as an excellent platform molecule for synthesis of probes in different application fields; the high-sensitivity hydrogen
