Large Magnetocaloric Effect in a Ferromagnetically Coupled [Mn3Gd] Complex With a Spin Ground State of S = 11

open access: yesChemistry – A European Journal, EarlyView.
Systematic studies of a series of new 3d–4f tetranuclear complexes revealed that the ferromagnetically coupled [Mn3Gd] complex exhibits large magnetic entropy changes, especially at higher temperatures and under lower magnetic fields. ABSTRACT A series of 3d‐4f heterometallic tetranuclear complexes, (TEA)[Mn3Gd(L)3(NO3)4(CH3CN)2] ([Mn3Gd]), (TEA)[Mn3La(

Chiral Dipicolinamide‐Based Push–Pull π‐Conjugated Systems as Nonreciprocal Circularly Polarized Luminescence Emitters

open access: yesChemistry – A European Journal, EarlyView.
This work presents the synthesis and characterization of chiral dipicolinamide push–pull fluorophores. While possessing similar photophysical properties in solution, their solvent‐annealed thin films exhibit unexpected, nonreciprocal chiroptical activity in both absorption and emission, including a complete inversion of the chiroptical profile upon ...

Persilylated and Related Silyl Anion‐Induced Synthesis of Group 3–10 Metal–Silyl Complexes

open access: yesChemistry – A European Journal, EarlyView.
Persilylated and related silyl anions serve as powerful tools for constructing metal–silyl complexes across group 3–10 elements. Their strong σ‐donating ability and steric bulk stabilize low‐coordinate, reactive species and enable unique bonding motifs.

X‐Ray Absorption Sensitivity at 5d$5d$ Edges of High‐Valent Light Actinides to Crystal‐Field Strength and Covalency Effects

open access: yesChemistry – A European Journal, EarlyView.
Analysis of x‐ray absorption spectra of U(VI) and U(V) oxides indicates an important role of U 5f−O$5f-\rm{O}$ 2p$2p$ charge transfer for increasing the 5f$5f$ occupancy and thereby affecting the ground state properties. ABSTRACT The 5f$5f$ states were probed in ThO2$\rm{ThO}_2$ and U(VI) and U(V) oxides using x‐ray absorption spectroscopy at the ...

A Solid‐Phase Approach to Chiral C2‐Substituted Cyclen and DOTA‐Like Lanthanoid Ligands

open access: yesChemistry – A European Journal, EarlyView.
Chiral C2‐substituted cyclen derivatives have been designed and synthesized from chiral cyclic peptoids. Their conversion into the corresponding DOTA‐type ligands opens new avenues for the development of high‐relaxivity MRI contrast agents. ABSTRACT Magnetic resonance imaging (MRI) is a powerful diagnostic modality that relies on Gd+3‐based contrast ...

Recent Advances of Perovskite Oxides for Air Pollution Control Chemistry: The Closed Loop From Design to Application

open access: yesEcoEnergy, EarlyView.
This review summarizes a descriptor‐guided framework for linking theoretical calculations, in situ/operando characterization, synthesis regulation, and application screening in functional materials. Emphasis is placed on dynamic structure–property relationships that enable low‐cost material design with enhanced activity, stability, and environmental ...
