TL;DR: It is demonstrated that porphyrins can be used as efficient cross-linkers to generate a new class of hydrogels with enabling optical properties and creates opportunities for new polymer designs with strong optical character.
Journal ArticleDOI
Oxidation of organic substrates catalyzed by a novel mixed-ligand ruthenium(III) complex
TL;DR: In this article, a mechanism involving formation of and transfer from a reactive high valent Ru(V)-oxo species as catalytic intermediate is proposed for the catalytic processes, which leads to the higher affinity of hydrogen atom/hydride abstraction than oxo-transfer to CC double bond.
Journal ArticleDOI
Enantio- and Regioselective Epoxidation of Olefinic Double Bonds in Quinolones, Pyridones, and Amides Catalyzed by a Ruthenium Porphyrin Catalyst with a Hydrogen Bonding Site
TL;DR: DFT calculations support the hypothesis that the reaction occurs via a hydrogen-bound transition state, in which the 3-alkenylquinolone adopts an s-trans conformation, and reveal that this transition state is preferred over a competing s-cis transition state because it exerts less strain in the rigid backbone and because the hydrogen bond interaction is more stable.

Highly Reactive Porphyrin-Iron-Oxo Derivatives Produced by Photolyses of Metastable Porphyrin-Iron(IV) Diperchlorates
TL;DR: On the basis of their unique UV-visible spectra, high reactivities, and oxo-transfer properties, the new transients are tentatively identified as porphyrin-iron(V)-oxo perchlorates, electronic isomers (or valence tautomers) of well-known iron(IV-oxo porphirin radical cations.

TL;DR: This multitechnique study combines scanning tunneling microscopy results with near-edge X-ray absorption fine-structure (NEXAFS) andX-ray photoelectron spectroscopy (XPS) data whose interpretation is supported by density functional theory calculations.
