Angewandte Chemie, EarlyView.A spodium bond (SpB) is defined as the net attractive interaction between a Group 12 element acting as a Lewis acid and electron‐rich atoms (Lewis bases or anions). These noncovalent interactions involve antibonding Sp–ligand orbitals and are markedly different from coordination bonds. Evidence for SpBs is provided by … [Weiterlesen...] Infos zum Plugin Spodium Bonds: Noncovalent Interactions Involving Group 12 Elements

Modulating Benzothiadiazole‐Based Covalent Organic Frameworks via Halogenation for Enhanced Photocatalytic Water Splitting: Small Changes Make Big Differences
Angewandte Chemie, Accepted Article.Two‐dimensional covalent organic frameworks (2D COFs), which is an emerging class of crystalline porous polymers, have been recognized as a new platform for efficient solar‐to‐hydrogen energy conversion owing to their pre‐designable structures and tailor‐made functions. Herein, we demonstrate that slight … [Weiterlesen...] Infos zum Plugin Modulating Benzothiadiazole‐Based Covalent Organic Frameworks via Halogenation for Enhanced Photocatalytic Water Splitting: Small Changes Make Big Differences
Expanding the Synthesis Field of High‐Silica Zeolites
Angewandte Chemie, EarlyView.Zeolite synthesis in an acidic medium is investigated. The isoelectric point (IEP) of the silica source is found to be the critical factor controlling the zeolite formation under acidic conditions. The zeolite crystalizes solely at a pH above the IEP when the silica particles are negatively charged. Abstract Aluminosilicate zeolites are … [Weiterlesen...] Infos zum Plugin Expanding the Synthesis Field of High‐Silica Zeolites
Copper‐Catalyzed Deaminative Difluoromethylation
Angewandte Chemie, EarlyView.An efficient Cu‐catalyzed approach is reported that enables the conversion of alkyl pyridinium salts, which can be readily synthesized from the corresponding alkyl amines, to their alkyl difluoromethane analogues. This method can be applied to the late‐stage modification of complex amino‐containing pharmaceuticals. Abstract The … [Weiterlesen...] Infos zum Plugin Copper‐Catalyzed Deaminative Difluoromethylation
N‐Annulated Perylene Bisimides to Bias the Differentiation of Metastable Supramolecular Assemblies into J‐ and H‐Aggregates
Angewandte Chemie, EarlyView.The distinctive self‐assembling features of N‐annulated perylene bisimides 1 and 2 are reported. Diester 1 , with no H‐bonding interaction operating, affords stable cooperative J‐type supramolecular polymers. The incorporation of amide functional groups in 2 results in a stimulating differentiation with several pathways … [Weiterlesen...] Infos zum Plugin N‐Annulated Perylene Bisimides to Bias the Differentiation of Metastable Supramolecular Assemblies into J‐ and H‐Aggregates
