Substituent‐Dependent SERS Kinetics of Citrate‐Stabilized Gold Nanoparticles: Balancing Hotspot Formation and Colloidal Flocculation

Chemistry – A European Journal, EarlyView.
Reporter chemistry controls the operational window of liquid‐phase SERS. Para‐substituted benzenethiols induce distinct AuNPs colloidal regimes, ranging from delayed but stable hotspot formation to rapid flocculation‐dominated signal decay. The balance between SERS‐active‐state formation and colloidal loss defines whether a reporter provides reliable ...

Bis(2‐Adamantyl)Magnesium: Synthesis, Structure, and Applications of a Versatile and Shelf‐Stable 2‐Adamantyl Anion Equivalent

Chemistry – A European Journal, EarlyView.
At last, the long‐sought bis(2‐adamantyl)magnesium reagent has been prepared in high yield as a stable tetrahydrofuran/dioxane adduct and fully characterized by x‐ray crystallography. This potent nucleophile outperforms the corresponding Grignard in transmetallation and carbonyl addition reactions, opening new avenues in adamantyl organometallic and ...

Tailoring Liquid Crystalline Self‐Assembly and Photophysical Properties of Unsymmetrical Fluorenones via Polar Terminal Groups

Chemistry – A European Journal, EarlyView.
Novel liquid crystalline fluorenones bearing various head groups were synthesized and characterized. By alteration of the head group, N, SmC, or SmA phases were obtained, and emission properties could be tuned depending on solvent or temperature. ABSTRACT In this work, a series of novel unsymmetrical fluorenone derivatives bearing various head groups ...

Non‐Covalent Fluorine–Silica Anchoring of a Molecular Platinum(II) bis(NHC) Catalyst: Structure, Interface Control, and Hydrosilylation Activity

Chemistry – A European Journal, EarlyView.
A Pt(II) bis(NHC) complex is immobilized on mesoporous silica through directional F–Si interactions encoded in the ligand framework. Quantitative 19F{29Si} REDOR experiments and molecular dynamics simulations establish Å‐scale catalyst–support contacts and define the interfacial organization.
