Light‐harvesting MOFs: A new porous porphyrinic metal–organic framework (MOF; see picture) was obtained by hydrothermal synthesis. The chemical and thermal stability of the material allows a postsynthetic insertion of zinc in the center of the porphyrin. The visible‐light photocatalytic activity of this porphyrin‐based material is shown for the sacrificial hydrogen evolution from water.

Targeted modification of electronic structure is an important step in the optimization of metal–organic frameworks (MOFs) for photovoltaic, sensing, and photocatalytic applications. The key parameters to be controlled include the band gap, the absolute energy position of band edges, the excited state charge separation, and degree of hybridization between metal and ligand sites. Partial metal replacement, or metal doping, within secondary building units is a promising, yet relatively unexplored route to modulate these properties in MOFs. Therefore, in the present study, a general method for selecting metal dopant is worked out in theory and validated by experiment, retaining MIL-125 and UiO-66 as the model systems. Metal mixing enables targeted optimization of key electronic structure parameters. This method is applicable to any MOF architecture and can serve as a roadmap for future synthesis of MOFs with predefined properties.

Pyrene-based MOFs have several applications; including luminescence, photocatalysis, adsorption and separation, heterogeneous catalysis, electrochemical applications and bio-medical applications.

Lichtsammelnde MOFs: Ein neues Porphyrin‐haltiges Metall‐organisches Gerüst (MOF; siehe Bild) wurde durch Hydrothermalsynthese erhalten. Die chemische und thermische Stabilität des Materials ermöglicht es, Zink nachträglich in das Porphyrin‐Zentrum einzuführen. Die photokatalytische Aktivität dieses Porphyrin‐basierten Materials im sichtbaren Bereich wird anhand der Entwicklung von Wasserstoff aus Wasser gezeigt.
