Quantifying Magnetic Anisotropy of Ferroelectric Fe(II) Square‐Pyramidal Systems Using Torque Magnetometry

Advanced Science, EarlyView.
Five‐coordinate, square‐pyramidal Fe(II) complexes adopting polar, non‐centrosymmetric crystal structures exhibit exceptionally large easy‐axis magnetic anisotropy. Ligand‐driven distortions critically control the anisotropy, and the dielectric, Polarization vs Elecric field and piezo response studies confirm intrinsic polarization, positioning these ...

Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

Advanced NanoBiomed Research, EarlyView.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are

Steuerung der Rotation eines Guanidiniumkations durch Kation‐π‐Wechselwirkungen

Angewandte Chemie, EarlyView.
Ein Lanthanid‐π‐Container wurde für die Bindung eines Guanidiniumkations in dessen aromatischer Kavität mittels Kation‐π‐Wechselwirkungen verwendet. Röntgenkristallographie und Festkörper‐NMR‐Spektroskopie bei schneller Rotation um den magischen Winkel wurden verwendet, um die zugrundeliegenden Wirt‐Gast‐Interaktionen zu untersuchen.
