Dipole Polarizabilities of Fluorinated Hydrocarbons

Croatica Chemica Acta, 2009
Dipole polarizabilities of fluorinated C2 and C3 hydrocarbons have been studied using Coupled Cluster theory including single, double and non-iterative triple substitutions (CCSD(T)) – in conjunction with three basis sets: Pol, Z3Pol and HyPol. All molecular geometries were optimized at the MP2/aug-ccpVTZ level.

Synthesis of Polycyclic Aromatic Hydrocarbons Decorated by Fluorinated Carbon Acids/Carbanions

, 2021
The carboarylation reaction of biphenyl‐alkynes was successfully triggered by electrophilic attack of 1,1‐bis(triflyl)ethylene on the alkyne moiety to give polycyclic aromatic hydrocarbons (PAHs) decorated by superacidic carbon acid functionality ...

Fluorinated Polymer Zwitterions: Choline Phosphates and Phosphorylcholines

, 2021
Among zwitterionic structures, the choline phosphate (CP) group is uniquely attractive for its ability to access novel chemical compositions that embed functional groups directly into the zwitterionic moiety.

Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

Angewandte Chemie, EarlyView.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

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

Angewandte 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 (
