, 2001 New oxygen-bridged norbornane-fused cyclobutene epoxides and bis-(cyclobutene epoxides) are described and shown to react stereoselectively with 7-azanorbornenes to produce syn-facial N,O-bridged polynorbornanes and stereorandomly with 7-oxanorbornenes to

Intermediality refers to the interconnectedness of media that depend on, refer to and interact with each other, both explicitly and implicitly (Jensen, 2008) and can be regarded as part of the emergence of a post-human entanglement of living bodies with ...

Sterisch überfrachtete Alken‐Photo‐Redox‐Schalter auf Basis von Chinolinium/Carben Bausteinen
Angewandte Chemie, EarlyView.Eine modulare Synthese einer neuen Klasse von Photo‐ und Redox‐Schaltern wird beschrieben, die auf der Kombination von Chinoliniumsalzen und Carbenen basiert. Das photochemische Schalten ermöglicht einen selektiven Wechsel zwischen gefalteten E/Z‐Isomeren, während das elektrochemische Schalten den Wechsel zwischen neutralen, radikalkationischen und ...

Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges
Angewandte Chemie International Edition, EarlyView.Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.

A Chiral Saddle‐Shaped Nanographene With Two Heptagon‐Embedded [4]Helicenes
Angewandte Chemie International Edition, EarlyView.We present a novel synthetic strategy toward a chiral saddle‐shaped nanographene (cSNG) via a two‐step oxidation of a prochiral anthracene precursor. The Scholl‐type oxidation first yields a key intermediate with sp3‐defect heptagons, and subsequent oxidative dehydrogenation affords fully conjugated cSNG.

Overcrowded Alkene Photo‐Redox‐Switches Based on Quinolinium/Carbene Building Blocks
Angewandte Chemie International Edition, EarlyView.A modular synthesis of a new class of photo‐ and redox‐switches is described based on the combination of quinolinium salts and carbenes. Photochemical switching allows to selectively switch between folded E/Z isomers, while electrochemical switching allows to change between neutral, radical cation and dicationic oxidation states, which are all isolable

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Silver nanoparticles (Ag NPs) have garnered attention for their environmental and medicinal potential, emphasizing the need for eco‐friendly synthesis. This study produces Ag NPs by reacting silver nitrate with aqueous Senegalia catechu leaf extract, a reductant and stabilizer.
