Oct 6, 2016 · The sequential introduction of substituents at the meso-positions enabled the synthesis of a variety of porphyrins such as push–pull type porphyrins and a number of unique …

Porphyrins (/ ˈ p ɔːr f ər ɪ n s / POR-fər-ins) are a group of heterocyclic, macrocyclic, organic compounds, composed of four modified pyrrole subunits interconnected at their α carbon …

Dec 9, 2020 · The affinities of porphyrin with seven types of substituents (–H, –OH, –tBu, –COOH, –NH2, –OCH3, –SO3−) on para position of meso-phenyl porphyrin toward gas molecules in …

Porphyrin is defined as an aromatic heterocyclic compound with a planar structure containing a macrocycle of 20 carbon atoms, 4 nitrogen atoms, and 22 π-electrons. These compounds are …

Jan 8, 2025 · Porphyrins bearing the unique 18π electron tetrapyrrolic macrocycles exhibit interesting photophysical and photochemical properties and have been considered as …

Feb 1, 2015 · Although usual water-solubilization of porphyrins has been achieved by an introduction of an ionic group such as ammonium, pyridinium, sulfonate, phosphonium, or …

Despite the contrasting nature of the SO3 fifth ligand of the porphyrin mimic to the native cysteine ligand, found in the P450 enzyme, the results from subsequent catalytic oxidations showed a …

Herein, a novel water-soluble 5,10,15,20-tetrakis (4-methoxyphenyl-3-sulfonatophenyl) porphyrin (TMPPS) was synthesized with 95% yield by modifying the traditional sulfonation route. The …
