Abstract Mechanical expansion and contraction of pores within photosynthetic organisms regulate a series processes that are necessary to manage light absorption, control gas exchange, water loss. These pores, known as stoma, allow the plant maximize output depending on environmental conditions such intensity, humidity, temperature by actively changing size stomal opening. Despite advances in artificial systems, little is about effect mechanical actuation synthetic materials where chemical...
Enantioselective electrophilic aromatic nitration methodology is needed to advance chirality-assisted synthesis (CAS). Reported here an enantioselective strategy operating with chiral diester auxiliaries, and it provides of a C3v -symmetric tribenzotriquinacene (TBTQ). These axially-chiral structures are much sought-after building blocks for CAS, but they were not accessible prior this work in enantioenriched form without resolution enantiomers. This controls the stereochemistry threefold...
The solar generation of H 2 in hydrogel materials is controlled by mass-diffusion at a length scale where 3D printing could be used to optimize porosity.

This work presents the first transition metal-free synthesis of oxygen-linked aromatic polymers by integrating iterative exponential polymer growth (IEG) with nucleophilic substitution (S N Ar) reactions. Our approach applies methyl sulfones as leaving groups, which eliminate need for a metal catalyst, while also providing flexibility in functionality and configuration building blocks used. As indicated 1) 1 H- H NOESY NMR spectroscopy, 2) single-crystal X-ray crystallography, 3) density...
Molekulare Kranausleger liefern in stereoselektiver Weise Nitroniumionen zu spezifischen Stellen konkaven polyaromatischen Systemen. S. T. Schneebeli und Mitarbeiter beschreiben ihrer Zuschrift auf 1047, wie die ersten enantioselektiven Nitrierungsreaktionen mithilfe solcher erreicht wurden. Die Ergebnisse stellen einen Durchbruch dar, da sie es ermöglichen, eine der ältesten Reaktionen nun enantioselektiver durchzuführen.
