摘要: The synthesis of a new compound, 10-(4-aminophenyl)-5,15-dimesitylcorrole, and its application for the preparation optical chemical pH sensors is described. dye materials were immobilized in sol–gel glass matrix characterised upon exposure to aqueous buffer solutions. response sensor based on fluorescence intensity changing corrole owing multiple steps protonation deprotonation. Due containing several proton sensitive centers, 10-(4-aminophenyl)-5,15-dimesitylcorrole optode shows wider range toward than that tetraphenylporphyrin (TPPH2) 5,10,15-tris(pentafluorophenyl)corrole (H3(tpfc)). It linear 2.17–10.30. effect composition membrane has been studied experimental conditions optimized. showed good reproducibility reversibility, common co-existing inorganic ions did not show obvious interference measurement.
