Synthesis, Photochemistry, and Molecular Structures of Peripherally-Molybdenated Tetraphenylporphyrins and -metalloporphyrins

Merging Porphyrins with Organometallics: Synthesis and Applications

“…Efficient electron transfer from the ferrocene to the excited singlet zinc porphyrin was observed, which, upon axial ligation to Lewis bases 52-56, generated the Fc + -ZnP:C 60 C À species. The supramolecular interaction was expanded by equipping ferrocene-functionalized zinc(II) and magnesium(II) porphyrins with a crown ether moiety (51). [110] Supramolecular complexes are formed (for instance 51 Zn:55) when these compounds are subjected to fullerenes bearing primary ammonium groups (54)(55)(56).…”

“…Porphyrins have been functionalized with, for instance, crown ethers, [16] phosphines, [17][18][19][20] pyridines, [21][22][23][24][25][26][27][28][29][30] bipyridines [31][32][33] /phenanthrolines, [34][35][36][37][38] terpyridines, [39][40][41][42][43] carboxylates, [44,45] imidazoles, [46] and other porphyrins. [21,[47][48][49][50][51][52] Another interesting example is given by the N-confused porphyrins, in which one pyrrole ring is flipped. These compounds can accommodate a metal within the porphyrin system while simultaneously acting as a monodentate ligand by virtue of the peripheral nitrogen atom.…”

Microwave-assisted synthesis and reverse saturable absorption of phthalocyanines and porphyrins

“…In this paper, the procedure for preparation of phthalocyanines and porphyrins, including dehydrobromonation, tetracyclomerization, dehydration, and replacement of protons to metal ions as shown in Schemes 1-4, take only 5-10 min. However, the conventional methods take several hours to one day for completion [12][13][14][15]. Microwave irradiation accelerates the polarization of the starting materials to promote the reactions.…”

“…However, the RSA of phthalocyanines and porphyrins in the thin solid film are less studied. Furthermore, the conventional syntheses for both of these two materials are time-consuming [12][13][14][15].…”

<b>Synthesis, characterization and electrochemistry of heterobimetallic complexes containing molybdenum(II) nitrosyl and manganese(II)-schiff base centers</b>

“…[Mo(NO)T p * Cl 2 ] T p * = tris (3,5-dimethylpyrazolyl) borate, a well characterized and readily synthesized precursor compound, affords a convenient vehicle for generating polynuclear bimetallic species that exhibit interesting redox, photochemical and optical properties [11]. Compounds containing these fragments linked by (OC 6 H 4 O) 2and (NHC 6 H 4 NH) 2-bridging ligands between two molybdenum centres have been synthesized.…”
