Rhenium in the core of porphyrin and rhenium bound to the periphery of porphyrin: synthesis and applications

Abstract

An overview of most of the well known rhenium porphyrins is presented reviewing their synthesis, coordination chemistry, and applications. The chemistry of some recently known porphyrin-Re conjugates is also discussed.

Meso-tetra(4-sulfonatophenyl)porphyrin silver/Ag nanoparticles/graphene-phase C3N4 with a sandwich-like structure and double-faced active centers via two-step room-temperature photocatalytic synthesis for ractopamine detection

“…11 Porphyrins as electron-rich organic molecules are characterized by remarkably high extinction coefficients in the visible region. 12,13 They are one of the most promising components of new materials for future electronic devices. For example, meso-tetra (4-sulfonatophenyl) porphyrin (H 2 TPPS 4 ), a water-soluble porphyrin with hydrophily grounds and light-harvesting capacity, 14 is beneficial to using photocatalytic synthesis to prepare novel materials with specific features.…”

Crystal structure of fac-tricarbonyl-(nitrato-k1 O)-bis(pyridine-κN)-rhenium, C13H10O6N3Re

“…Several classes of rhenium based radiopharmaceuticals exists varying from small molecules, colloids, peptides to antibodies, each of which are coordinated or labelled differently with the rhenium metal centre and are distributed in various ways through the body to the potential disease site, whether it is cancer, arthritis, etc. all of which speaks to the versatility of rhenium-based radiopharmaceuticals [11,12]. Aside from the direct use of the radioactive isotope, the nonradioactive rhenium can be used as a chemical analogue to the short-lived isotope of technetium namely, 99m Tc, which is widely used in the medicinal world today [13].…”

Rhenium Biscorrole Sandwich Compounds: XAS Evidence for a New Coordination Motif

“…In summary, the high-temperature interaction of Re 2 (CO) 10 with three free-base meso -triarylcorroles has led to the isolation of neutral rhenium corrole sandwich compounds with the molecular formula ReH­[T p XPC] 2 , a heretofore unprecedented coordination motif in the field of rhenium–porphyrinoid interactions. , DFT calculations and Re L 3 -edge EXAFS studies support a seven-coordinate rhenium center and one loosely interacting NH group. The extra hydrogen can be removed by a base, resulting in dramatically sharper UV–vis spectra consistent with C 2 -symmetric {Re­[T p XPC] 2 } − anions.…”

“…The interaction of rhenium with porphyrin-type ligands has resulted in a growing variety of coordination motifs in recent years. , Thus, porphyrins and related ligands (such as sapphyrin , and triphyrin) act as tridentate ligands toward the [Re­(CO) 3 ] + fragment to yield unusual “capped” organometallic complexes that obey the 18-electron rule. Likewise, 99 Tc­(CO) 3 -capped porphyrin derivatives are also well-known .…”
