Post 1: March 13th: Review by M. Senge on the shape of porphyrins : structure-properties relationships (Submitted by C. Gros who finds this review quite exhaustive)

Post 2: March 13th: Review by M. Senge on porphyrin and porphyrinoid
total synthesis and biosynthesis (Submitted by C. Gros who finds this review quite exhaustive)

Post 3: April 7th: Inorg. Chem. 1 et Inorg. Chem. 2 Two  articles from the group of J. Mayer (Yale) describing an in-depth study of the role played by charged substitutents in the second coordination sphere of an iron porphyrin (Fe(o-TMA)) known for its catalytic properties in the reduction of CO2 or O2. These results are an exceptional contribution to the design of ligands bearing electrostatic substituents which are trendy in molecular catalytic processes and metal complex reactivity in general.

Post 4: June 17th (by Bernard Boitrel) Ceux qui s’intéressent de près à l’analyse des déformations des porphyrines ont très certainement apprécié l’alerte de Claude Gros concernant le travail de M. Senge (Dublin) relatif à la mise en ligne d’une nouvelle version de NSD, initialement publié par Shelnutt en 1994. En effet, depuis 2014, NSD original n’était plus accessible en ligne…

Le problème de NSD est qu’il est limité au macrocycles porphyriniques réguliers.

Voici une nouvelle contribution de M. Broering (Université de Braunschweig), avec “PorphyStruct” qui a l’avantage d’être plus flexible et de travailler sur les porphyrines, corroles, norcorroles, porphycènes et corphycènes, bref à peu près tous les macrocycles TETRA-pyrroliques.

J’ai téléchargé le logiciel ; je vais essayer de le tester en détails.

Bonne lecture.

Post 5: April 6th, 2022 (by Philippe Arnoux)

Thanks to a piece of specific equipment installed on the TEMPO beamline by Sorbonne University, researchers from the University of Trieste have shown that the presence of oxygen gas facilitates the porphyrin metalation step, which can thus take place at room temperature.

This result allows to consider new processes of metallization of organic structures on surfaces and, in the case of metalloporphyrins, could lead to the synthesis of molecules used for example for photocatalysis (conversion of solar energy), the production of hydrogen from water (water splitting), the design of biosensors ….
