Özet
The structural elucidation and syntheses methods of new peripherally tetra-substituted MPcs [Cu-II (6), Co-II (7), MnClIII (8), and Ni-II (9) phthalocyanines] carrying 4-methyl-N-(3-morpholinopropyl)benzenesul fonamide moieties were reported in the present study. The corroboration of the prepared compounds (3, 5, and 6 to 9) was made by LC-TOF/MS, UV-Vis, Fourier Infrared, H-1 NMR, C-13 NMR, and MALDI-TOF mass spectral data. Herein, we submit a new procedure that uses metallophthalocyanine complexes for the first time as spectrofluorimetric agents to detect and determine health-threatening food additive, Sudan II dye, with a new simpler, cheaper, and faster spectrofluorimetric method instead of time-consuming and expensive HPLC processes. Furthermore, the sensitivities of the proposed methods are good enough to determine the amount of dye at a concentration of 0.1 mg/L. The methods have LOD values between 0.035 and 0.050 mg/L. The linear ranges are found to be between 0 and 8.3 mg/L. The precision of the methods is determined to be between 1.1 and 2.4 as % RSD. Therefore, this study would make a good contribution to the food industry and phthalocyanine chemistry by detecting and determining the hazardous food colorant Sudan II with metal phthalocyanines.
