ChemistryOpen1,2‐Phenylene tetraurea macrocycles recently attracted attention as self‐assembled channel‐making compounds with high selectivity to chlorides. Here, we report on the introduction of aliphatic chains in the periphery of the 1,2‐phenylene tetraurea ...

Chemistry – A European Journal, EarlyView.Chemoenzymatic reactions using the siderophore synthetase DesD from Salinispora tropica and hydroxamic acid substrates (native, non‐native) with different multiplicities (monomer, dimer) and components (homo‐/heterodimer) followed different reaction trajectories, which biased the architectures of the chelator major products and indicated DesD contains ...

Chemistry – A European Journal, EarlyView.This is a comprehensive study of new family of high functionalized meso‐tetraarylporphyrins. A synthetic approach to phosphonate‐substituted fluorinated porphyrins was developed. These compounds were investigated with respect to singlet oxygen generation and photostability.

Isodesmic Supramolecular Assembly of Phenylethynylene Bis‐Urea Macrocycles
Chemistry – A European Journal, EarlyView.A soluble phenylethynylene bis‐urea macrocycle assembles in polar media via an isodesmic hydrogen bonded mechanism. Spectroscopic and morphological studies reveal nanoscale aggregates with short chain length, while guest additives modulate enthalpy and polymerization, demonstrating tunable supramolecular assembly.

Chemistry – A European Journal, EarlyView.DFT calculations on porphyrin, corrin, and corphin complexes of cobalt, rhodium, iron, manganese, or nickel, and QM/MM calculations on enzyme models, explore the factors controlling the availably of super‐reduced metal(I) states. True metal(I) states are seen in corrin only for cobalt, in corphin only for nickel, and not at all in porphyrin.

Metal‐Ion Regulated Light‐Free Z→E Isomerization of Azobenzene Glycomacrocycle
Chemistry – A European Journal, EarlyView.Metal ion‐catalyzed Z→E isomerization of photoswitchable azobenzene glycomacrocycle: A new azobenzene‐based glycomacrocycle is capable of forming a 1:1 complex with divalent metal ions in both E‐ and Z‐isomers. The complexes undergo light‐free Z→E isomerization in a timescale spanning from seconds to weeks.

Stepwise Synthesis of Tetrabenzotriazaporphyrins (TBTAPs) and Their Open 2‐ and 3‐Ring Fragments
Chemistry – A European Journal, EarlyView.Unexpected reaction pathways to porphyrin‐phthalocyanine hybrids are uncovered by the synthesis of “half‐macrocycle” fragments and subsequent macrocyclization. Rather than the expected 2:2 “ABBA” product, the 3:1 “ABBB” hybrid is isolated as the only macrocyclic product.
