摘要：

the present work, the classical synthesis method of 5,10,15,20-(4-sulphonatophenyl) porphyrin (TPPS4) was improved. The synthesis process became more environmentally friendly, and the yield was increased by 10%. We constructed a sensitive fluorescent sensor for detection hydrogen peroxide (H2O2) and glucose (C6H12O6) by using the hyperfluorescence of TPPS4. The TPPS4-Fe3+ complex system of the sensor could generate electron transfer process (ET) in the process of hydrogen peroxide (H2O2) and glucose oxidation, which quenched the TPPS4 fluorescence. The system had a linear range of 0-42 mu M for hydrogen peroxide, and the minimum detectable limit (LOD) was 1.24 nM (S/N = 3). Compared with other detection methods, the proposed method had the advantages of higher sensitivity, lower detection limit and more simple operation. (c) 2018 Elsevier B.V. All rights reserved.
