| Abstract: | A novel water-soluble porphyrin[5,10,15,20-tetra(3-ethoxy-4-hydroxy-5-sulfonate)phenyl porphyrin, H2TEHPPS] was designed and synthesized, which could be used as a potential fluorescence sensor to detect tempe- rature changes. The studies were performed in solution phase and the concentration of H2TEHPPS was 2.0×10-5 mol/L. The optical properties of H2TEHPPS were investigated based on the UV and fluorescence spectra. The results show that the fluorescence intensity of H2TEHPPS is directly proportional to temperature in the range of 293―353 K. So H2TEHPPS can be used as a molecular temperature sensor in biomedical and other fields. |
