Impacts of Fluorination at the Ortho‐Position of Carboxy Groups on Tetrakis(biphenyl)ethene‐Based Hydrogen‐Bonded Framework

Small, EarlyView.
This work provides new findings on the effect of fluorination on the substitution of TPE derivatives and the modulation of the structure and fluorescence properties of hydrogen‐bonded organic framework (HOF) of F‐CBPE. ABSTRACT Fluorination of building block molecules is one of the effective engineering approaches to modulate molecular assembly in ...

Fluorescence Sensing of Anions Like Adenosine 5ʹ‐Triphosphate With pH‐Gated Porous Dye‐Loaded Cerasomes

Small, EarlyView.
The development of gated systems enabling controlled pore opening offers new opportunities for sensing applications. This study explores dye loading in porous and non‐porous cerasomes and pH‐dependent ATP‐triggered gating via polyamine anchors. Porous cerasomes were synthesized using block‐co‐polymers, enabling controlled proton influx and fluorescence‐

Rhodium Cluster Catalysts Enable Efficient Catalytic Hydroformylation in Mild Conditions: Cluster Size Dependence

Small, EarlyView.
Nanometer‐sized Rh clusters provide a specific reaction environment that facilitates the balanced co‐adsorption of styrene, CO, and H, thereby promoting hydroformylation. ABSTRACT The size of the reactive metal domain, termed an ‘ensemble’, in supported metal catalysts critically influences their catalytic activity.

Isolated Organosodium and ‐Potassium Intermediates: Understanding Metal Effects on Anionic Styrene‐Isoprene Copolymerization

Small, EarlyView.
Reactive organosodium and organopotassium intermediates of the anionic styrene and isoprene polymerization are presented. Crystal structures of alkoxide‐free intermediates are obtained by X‐ray diffraction, and their isolation enables kinetic polymerization studies.

Position Over Composition: Positional Isomerism Enables Encapsulation‐Independent Intrinsic Stability in a Conjugated Polymer

Small, EarlyView.
Repositioning side chains (para→meta) provides a composition‐invariant handle to program conjugated‐polymer chain geometry. The resulting worm‐like, kink‐suppressed conformation delivers >5× higher intrinsic photostability and enhanced resistance to energetic particle damage.
