Antiaromaticity‐Driven Enhancement of Single‐Molecule Electrical Conductance by s‐Indacene Molecular Bridges

open access: yesAngewandte Chemie, EarlyView.
Within the same molecular length scale, antiaromatic s‐indacene exhibits a marked increase in conductance compared to its aromatic benzodithiophene counterpart. Notably, the inherently small HOMO–LUMO gap of antiaromatic systems maintains a certain level of conductance even in the presence of cross‐conjugation.

Anionic T‐Shaped Platinum(0) Pincer Complexes and Platinum(I) Intermediates in Radical Reactions With Alkyl Halides

open access: yesAngewandte Chemie, EarlyView.
Two anionic, T‐shaped, d10 platinum(0) complexes containing a PNP pincer ligand have been isolated and characterized. These complexes react with aliphatic C‐Br bonds under formation of a platinum(II) bromide and an alkyl complex, as well as the homocoupled hydrocarbons.

Development of Sub‐50 nm Core–Shell Silica Nanoparticles With Controlled In Vivo Behavior for 19F Magnetic Resonance Imaging

open access: yesAngewandte Chemie, EarlyView.
Ultrasmall PFCE‐loaded silica nanoparticles synthesized through a one‐pot double‐emulsion synthesis method, where rapid silica shell formation kinetically fixes droplet size. The resulting s‐FLAME nanoparticles enable strong 19F MRI signals with enhanced hepatic clearance rate and tumor‐accumulation performance. ABSTRACT 19F magnetic resonance imaging (

Crosslinking of Linear Polyimines Into Aminal‐Linked Porous Organic Polymers for C2 Hydrocarbon/Methane Separation

open access: yesAngewandte Chemie, EarlyView.
Crosslinking of linear polyimines with aromatic diamines via nucleophilic addition converts nonporous polyimine precursors into aminal‐linked porous networks, offering a new strategy for synthesizing porous organic polymers. The resulting materials exhibit high C2 hydrocarbon adsorption capacity, excellent selectivity over CH4, and durable cyclic ...

Iterative Synthesis of Pyrene–Coronene Molecular Graphene Nanoribbons

open access: yesAngewandte Chemie, EarlyView.
An iterative approach delivers a new family of undoped, cove‐edged graphene nanoribbons with lengths up to 9.1 nm that exhibit both molar absorptivity and fluorescence brightness values on the order of 105 M−1 cm−1 and an intrinsic charge‐carrier mobility of 475 ± 32 cm2 V−1 s−1.
