Biomimetic metalloporphines and metalloporphyrins as potential tools for delignification: Molecular mechanisms and application perspectives

Zinc(II) Tetraphenylporphyrin on Ag(100) and Ag(111): Multilayer Desorption and Dehydrogenation

“…2 Additionally, porphyrins are extremely versatile molecules that can be utilized to probe a variety of topics such as supramolecular chemistry, 3 biomimetic redox and rearrangement catalysis, 4 and molecular electronics such as organic light emitting diodes, 5 field-effect transistors, [6][7][8][9][10][11][12][13] and dye-sensitized solar cells. 14,15 One particularly interesting porphyrin derivative is tetraphenylporphyrin (TPP), which consists of a porphyrin macrocycle with four phenyl moieties bound to the carbon bridge between adjacent pyrrole groups, as shown in Figure 1a.…”

Catalytic oxidation of tetrabromobisphenol A by iron(III)-tetrakis(p-sulfonatephenyl)porphyrin catalyst supported on cyclodextrin polymers with potassium monopersulfate

“…Iron(III)-porphyrin complexes can be considered to be biomimetic models of oxidative enzymes such as ligninases and peroxidases [1], and can catalyze the oxidative degradation of halogenated phenols in the presence of an oxygen donor such as H 2 O 2 and KHSO 5 [2][3][4][5][6][7]. In this context, a water-soluble iron(III)-tetrakis(p-sulfonatephenyl)porphyrin (FeTPPS) has been employed in homogeneous catalytic systems for the oxidation of refractory halogenated phenols, such as pentachlorophenol, tetrachlorobisphenol A and tetrabromobisphenol A (TBBPA) [4][5][6][7].…”

Biomimetic Sulfide Oxidation by the Means of Immobilized Fe(III)‐5,10,15,20‐tetrakis(pentafluorophenyl)porphin under Mild Experimental Conditions

“…In our previous studies, we reported the immobilization of some metalloporphins onto solid supports emulating the structure of cytochrome P-450 and ligninolytic peroxidases. These catalytic adducts were able to oxidize both lignin model compounds (recently reviewed in [26]) and durable textile dyes [27][28][29].…”
