“…The spectro-electrochemical and acid–base properties of N 2 CPs and the photochemistry of their copper(III), silver(III), and gold(III) complexes were studied. − The X-ray crystal structures of the complexes revealed highly planar core geometries along with the presence of peripheral amine and imine nitrogen sites; the central metal affects the amphiprotic character of the complexes . Their syntheses, application as photosensitizers (for the adj -isomers) and as anion binders (binding to the peripheral nitrogen atoms), , and their metal coordination and supramolecular chemistry have been reviewed. − , …”

The replacement of one or more pyrrolic building block(s) of a porphyrin by a nonpyrrolic heterocycle leads to the formation of so-called pyrrole-modified porphyrins (PMPs), porphyrinoids of broad structural variability. The wide range of coordination environments (type, number, charge, and architecture of the donor atoms) that the pyrrole-modified frameworks provide to the central metal ions, the frequent presence of donor atoms at their periphery, and their often observed nonplanarity or conformational flexibility distinguish the complexes of the PMPs clearly from those of the traditional square-planar, dianionic, N 4 -coordinating (hydro)porphyrins. Their different coordination properties suggest their utilization in areas beyond which regular metalloporphyrins are suitable. Following a general introduction to the synthetic methodologies available to generate pyrrole-modified porphyrins, their general structure, history, coordination chemistry, and optical properties, this Review highlights the chemical, electronic (optical), and structural differences of specific classes of metalloporphyrinoids containing nonpyrrolic heterocycles. The focus is on macrocycles with similar "tetrapyrrolic" architectures as porphyrins, thusly excluding the majority of expanded porphyrins. We highlight the relevance and application of these metal complexes in biological and technical fields as chemosensors, catalysts, photochemotherapeutics, or imaging agents. This Review provides an introduction to the field of metallo-PMPs as well as a comprehensive snapshot of the current state of the art of their synthesis, structures, and properties. It also aims to provide encouragement for the further study of these intriguing and structurally versatile metalloporphyrinoids.

“…It is still essential to understand and study effective interaction between porphyrin and TMNPs. Our laboratory has long term interest in the synthesis of porphyrins, their precursors, and their applications . Hence, in the present study, we first report tetrahydroxyphenylporphyrin (TPP‐OH)‐stabilized Au‐, Ag‐ and PdNPs and their applications in the reduction of 4‐nitrophenol and production of hydroxyl radicals.…”

The synthesis of robust transition metal nanoparticles (TMNPs) are still intensively investigated because of multiple up-to date applications in catalysis, solar cells, nonlinear optics, biological labeling, nanoelectronics, medicine and energy storage devices. Here we report synthesis of tetrahydroxyphenylporphyrin (TPP-OH)-stabilized TMNPs (including AuNPs, AgNPs and PdNPs) by mixing TPP-OH and simple commercial metal salt and followed by the addition of sodium borohydride [a] College

“…223,253 A reaction of S98-3 with [AuCl(S(CH 3 ) 2 )] yields an analogous gold(III) complex (S108-3), yet to conduct gold(III) insertion, preceding bromination of inner CH positions is necessary. 253 cis-Diazuliporphyrin S100-1, after deprotonation, is dianionic. Thus, it is a suitable platform to accommodate a palladium(II) ion.…”
