Disclosed are HPTS series derivatives and a synthesis method thereof, belonging to the field of organic synthesis. The HPTS series derivatives are prepared by introducing alkylamine or alcohol into sulfonic acid groups of HPTS. The synthesis method comprises the following steps: subjecting HPTS and phosphorus oxychloride to heating and reflux reaction for 12 hours under catalysis of DMF to obtain a reaction product; introducing the reaction product into ice water, stirring, precipitating solid, and performing suction filtration to obtain HPTS-SO.sub.2Cl; dissolving the HPTS-SO.sub.2Cl in tetrahydrofuran to prepare solution A, and dissolving alkylamine or alcohol in tetrahydrofuran to prepare solution B; mixing the solution A with the solution B and then reacting for 24 hours at normal temperature, obtaining a product by rotary evaporation, and obtaining a pure compound after separation through columns. The derivatives have strong fat solubility, overcome the defect of a very strong water solubility.

The present invention provides a fluorescent dye HPTS-lipo for monitoring two-dimensional pH value, a fluorescent sensing film, and use thereof, belonging to the field of two-dimensional pH value monitoring. The fluorescence sensing film for monitoring two-dimensional pH is prepared from the fluorescent dye HPTS-lipo, and HPTS-lipo is embedded by hydrogel D4 in a preparation process.
