Nov 18, 2015 · In this chapter, we discuss IR and Raman spectra of protonated, deuterated, and meso ‐substituted parent porphyrin using density functional theory (DFT) to calculate the IR and Raman spectra, and, where possible, make comparison to experimental spectra.

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 that were applicable to photodynamic therapy and in multichromophores.

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 atoms via methine bridges (=CH−).

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 adsorption process were studied in different size of boxes …

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 highly versatile and can be chemically modified for various applications in fields such as solar cells, biomedicine, and catalysis.

Jan 8, 2025 · Porphyrins bearing the unique 18π electron tetrapyrrolic macrocycles exhibit interesting photophysical and photochemical properties and have been considered as promising ligands for the construction of functionalized metal–organic frameworks (MOFs).

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 carboxyl to porphyrin ring, we proposed the preparation of water-soluble P and Sb porphyrins by modification of axial ligands.

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 very good degree of similarity.

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 reaction of TMPPS with AgNO 3 afforded AgTMPPS …

Jul 23, 2019 · We report that Mn(IV)-oxo porphyrin complexes, Mn IV (O)(TMP) (1) and Mn IV (O)(TDCPP) (2), are capable of activating the C–H bonds of hydrocarbons, including unactivated alkanes such as cyclohexane, via an oxygen non-rebound mechanism.
