Herein, porphyrin-conjugated organic polymers, Mn(iii)P-CMP and Fe(iii)P-CMP, were synthesized by Suzuki coupling reaction with manganese/iron tetraphenylporphyrin (T(p-Br)PPMn/FeCl) and 1,4-phenyldiboronic acid as building blocks. The structures of the p

Mono-, tetra-, and octa-bromo substituted Mn(II)- and Mn(III)-tetraarylporphyrins were synthesized by reactions of manganese(II) chloride with corresponding porphyrin ligands or their Cd(II)-complexes in DMF. With the use of the metal exchange reaction, the time of the Mn-porphyrins formation is significantly reduced with increase in yield of final products in comparison with the complexation reaction. Mn(III)-tetraarylporphyrins reduce to the Mn(II)-porphyrins in DMF in the presence of NaOH and in pure DMF. The obtained compounds were identified using UV–vis and 1H NMR spectroscopy, mass-spectrometry, and elemental analysis.

As an extension of our study to reveal the effect of porphyrin deformation on the 13C and 1H NMR chemical shifts, both five-and six-coordinate high-spin (S = 2) Mn(III) complexes such as Mn(Por)Cl and [Mn(Por)(CD3OD)2]Cl h

Spectrophotometry was applied to study of the kinetics of dissociation and state in concentrated sulfuric acid solutions of bromine-substituted manganese(III) tetraphenylporphyrins featuring σ,π donor-acceptor metal-nitrogen interaction. The effects of identical substituents in the pyrrole and phenyl rings of the ligand on the kinetic stability of the tetraphenylporphine complexes differ not only quantitatively, but can be opposite in sign. A mechanism is considered of the electronic effects of substituents on the state of the electron pairs of the Mn-N bonds and of the n-electron pairs of the nitrogen atoms which add protons in the course of dissociation of the complex. These effects are unsimilar for subsituents in the macroring and in the phenyl rings of the ligand tetraphenylporphine.
