Exploring the Effects of Axial Pseudohalide Ligands on the Photophysical and Cyclic Voltammetry Properties and Molecular Structures of MgII Tetraphenyl/porphyrin Complexes

“…Our synthetic strategy uses either crypt‐222 or 18‐crown‐6 (18‐C‐6) to solubilize MX salts (M = K, Na; X = anion) in organic solvents. Several metalloporphyrins containing anionic ligands such as CO 3 2– and N 3 – were prepared by using this synthetic technique 9,10. We noticed that the use of 18‐crown‐6 could result in its coordination to the metal center of the metalloporphyrin as in {[Zn(TPP)(18‐C‐6)]} n 11.…”

Effect of the coordination of π-acceptor 4-cyanopyridine ligand on the structural and electronic properties ofmeso-tetra(para-methoxy) andmeso-tetra(para-chlorophenyl) porphyrin cobalt(ii) coordination compounds. Application in the catalytic degradation of methylene blue dye

“…The spectroscopic, structural, magnetic and electrochemical properties of metalloporphyrins involving several metal ions such as Fe(II), Fe(III), Zn(II), Cd(II), Sn(IV), Mg(II), Mn(III) and Co(II) have been investigated by our group for more than two decades. [1][2][3][4][5][6][7] The study of these tetrapyrrolic coordination compounds is of great importance because they provide good models for understanding the structural, electronic and magnetic properties of hemoproteins and heme-like enzymes such as cytochromes P450. Recently, porphyrins and porphyrin related compounds are nding crucial use in new applications such as catalysis in solar photovoltaic cells, [8][9][10] as chemical sensors 11,12 and as photosensitizing agents (PS) for photodynamic therapy (PDT).…”

“…Many studies on the 4-cyanopyridine ion iron(III) ion complex types [Fe III (Porph)(4-CNpy) 2 ] + , using the following four meso-porphyrins: (1) the unsubstituted meso-tetraphenylporphyrin (H 2 TPP), (2) the methyl para-substituted meso-porphyrin (the meso-tertratolylphenylporphyrin H 2 TTP), (3) the 2,3,4methyl para-substituted meso-porphyrin (the meso-tetramesitylporphyrin H 2 TMP) and (4) the OMe para-substituted mesoporphyrin (H 2 TMPP) have been carried out. 21,23 For these ferric low-spin metalloporphyrins, the very high ruffling of the porphyrin is related to the important p-acceptor character of the 4-CNpy axial ligand.…”
