Photodegradation of Rhodamine B using Aqueous Free-Base Porphyrin and Metalloporphyrins of Divalent Metal Ions

The present study is focused on the photodegradation of rhodamine B using aqueous free-base photocatalysts in presence of solar radiation. All catalysts such as free-base tetrasodium meso-tetra(p-sulphonatophenyl)porphyrin (TPPS4) or abbreviated as TPS and substituting M = Co, Ni, Cu, Zn and Ag into the moiety of TPS to get metalloporphyrins, were synthesized. Further, they were characterized by UV-visible, IR and 1H MMR spectroscopic techniques. The photodegradation of rhodamine B of concentration 10-5 M was carried out with 5 mg of a photocatalyst of free-base and other metalloporphyrins. It was observed that these synthesized photocatalysts have shown the photodegradation efficiency to the extent of 100% within time period of 5 to 40 min. The process of degradation was verified with HPLC and ion-chromatography.

Influence of charge and metal coordination of meso-substituted porphyrins on bacterial photoinactivation

The photodynamic effect of meso-substituted porphyrins with different charges and metal ions: meso-tetraphenylporphyrin tetrasulfonate 1, its nickel 2 and zinc complexes 3; meso-tetranaphthylporphyrin tetrasulfonate 4, and its zinc complex Zn 5; and tetra piridyl ethylacetate porphirins 6 and their nickel 7 and zinc 8 complexes, were synthesized and studied their antimicrobial activity against Escherichia coli. Fluorescence quantum yields (ΦF) were measured in water using reference TPPS4, obtaining higher values for complexes 3 and 4. The singlet oxygen ΦΔ were measured using histidine as trapping singlet oxygen and Rose Bengal as a reference standard. Complexes 1, 2 and 6 have the highest quantum yields of singlet oxygen formation, showing no relation with the peripheral charges and efficiency as Type II photosensitizers. Meanwhile complexes 3, 8 and 4 were the most efficient in producing radical species, determined with their reaction with NADH. The photoinduced antibacterial activity of complex was investigated at different concentrations of the photosensitizers with an irradiation time of 30 min. The higher antibacterial activities were obtained for the complexes 1-3 that are those with greater production of ROS and minor structural deformations. Complexes 7 and 8 had moderate activity, while 4-6 a low activity. Thus, in this work demonstrates that the production of ROS and structural deformations due to peripheral substituents and metal coordination, influence the activity of the complexes studied. Therefore, is important to perform comprehensive study physics and structurally when predicting or explain such activity.

Electrochemical and spectroelectrochemical studies of nickel(II) porphyrins in dimethylformamide

The electrochemistry of (P)NiII in DMF is reported where P is the dianion of tetrapyridylporphyrin (TpyP), tetrakis(p-(sodiosulfonato)phenyl)porphyrin (T(p-SO3Na)PP), and tetrakis(p-diethylaminophenyl)porphyrin (T(p-Et2N)PP). Each electrode reaction was monitored by cyclic voltammetry, rotating-disk voltammetry, spectroelectrochemistry, and ESR spectroscopy, and on the basis of these data, an overall oxidation-reduction mechanism for each complex is presented. All three compounds can be reduced by one electron to form π anion radicals or oxidized by one or two electrons to form π cation radicals and dications. Additional oxidations are also associated with the diethylamino groups on (T(p-Et2N)PP)Ni. Reduced (T(p-SO3Na)PP)Ni and (T(p-Et2N)PP)Ni are stable, but (TpyP)Ni undergoes demetalation after reduction by two electrons at the porphyrin π ring system. This is the first example for demetalation of an electroreduced nickel porphyrin and contrasts with results for other nickel porphyrins, which are quite stable after electroreduction. The effect of porphyrin ring structure on the electrochemical behavior of each complex is discussed and compared with that of other related metalloporphyrins.
