Electrochemical and spectroscopic studies of poly(diethoxyphosphoryl)porphyrins

Highly Proton‐Conductive Zinc Metal‐Organic Framework Based On Nickel(II) Porphyrinylphosphonate

“…Initial H 2 ‐TPPP and the corresponding nickel(II) complex were synthesized by literature methodologies . The treatment of nickel(II) porphyrin by TMSBr led to the formation of the target compound Ni‐H 8 TPPP in quantitative yield .…”

Survey of Synthetic Routes towards Phosphorus Substituted Porphyrins

“…It was already shown that the self assembling of these phosphoryl Zn(II) and Cu(II) porphyrins should be observed in solid state and in solution. [30][31][32]34,35] This self assembling leads to 1D and 2D networks. At last but not least, the new A 3 B type phosphorylated porphyrins should be very good precursors in order to construct efficient DSSCs and to develop photocatalysts.…”

“…Palladium-catalyzed phosphorylations both at the meso position of the porphyrin ring and at the p-bromophenyl substituents were described by Enakieva et al [30][31][32] The A 4 and A 2 B 2 porphyrin types were obtained, the A 2 B 2 type being isolated in modest to good yields depending of the reaction conditions (Scheme 16).…”

“…Indeed, a good yield of the 5,15-bis-(diethoxyphosphoryl)-10,20-diphenyl-porphyrinatozinc 37 (51 %) was described by Kadish et al when ethanol was used as a solvent and dibromide 34 as the precursor (Scheme 17). [31] Moreover, the phosphorylation reaction of the Zn porphyrin gave higher yield of the target product compared to the reaction involving the corresponding free base 36 as a precursor. A hydrodebromination reaction was also observed under these conditions giving the porphyrins without phosphoryl groups and the monophosphoryl derivatives (40-42).…”

“…[33] The A 2 B 2 type phosphorylated porphyrin 46 was obtained using the same conditions by phosphorylation of the tetrabrominated 45 precursor where two bromine atoms are directly linked to the macrocycle ring and another two bromine atoms through an aryl spacer (Scheme 19). [31] The first synthesis of zinc β-phosphorylporphyrins was reported by Vinogradova et al [34] β-Dialkoxyphosphoryl tetraphenylporphyrins and their Zn complexes were synthesized using Cu and Pd catalysts.…”
