Fine‐Tuning the Motion of Tetrafluoro‐1,4‐Benzoquinone Within Charge‐Transfer Cocrystals Through Variation of the Donor: An Entropic and Enthalpic Point of View

Chemistry – A European Journal, EarlyView.
Five CT cocrystals using TFBQ and fused, polycyclic donors derived from fluorene are synthesized. The π‐stacking in all cocrystals provides a platform for the displaying of in‐plane molecular motions of TFBQ, which is by supramolecular interactions.

A Family of Symmetrical and Unsymmetrical Aza‐Dipyrromethenes and Aza‐BODIPYs with Through‐Bond and Face‐to‐Face p‐Interaction Between Termini

Chemistry – A European Journal, Accepted Article.
The dipyrromethenes (DPMs) and their borylated adducts (BODIPYs) constitute a class of versatile chromophores that has become one of the most widely studied over recent decades. They combine excellent photochemistry properties with opportunity for synthetic manipulation and tuning.

A Tour in the Chemistry of a Tricoordinate Rh(−I) Complex

Chemistry – A European Journal, EarlyView.
The low‐coordinated Rh(−I) complex displays a nonconventional reactivity, affording a Rh(I) compound in a trigonal‐pyramidal geometry, a rare true metalloradical Rh(0) complex, a highly unsaturated 14 eV complex featuring a Rh − Si bond, and catalyzes a dimerization of aldehydes to the ester through a Rh(‐I)/Rh(I) catalytic cycle with catalyst ...

High Dispersion of Copper Nanoparticles on Carbon Black in Minimal Loadings Enhances the Electroreduction of CO2 to CO

Chemistry – A European Journal, EarlyView.
A few copper nanoparticles (less than 1 mg/cm2) supported on CB and deposited on a carbon‐based GDL can achieve Faradaic efficiencies exceeding 60% for CO formation at 100 mA/cm2 due to their homogeneous dispersion and separated catalytic sites. Abstract Electrochemical CO₂ reduction (ECR) offers a promising route for converting CO₂ emissions into ...
