Faithful Solid State Optical Memory with Dynamically Decoupled Spin Wave Storage

, 2013
We report an optical memory in a rare earth doped crystal with long storage times, up to 20 ms, together with an optical bandwidth of 1.5 MHz. This is obtained by transferring optical coherences to nuclear spin coherences, which were then protected ...

When Light Challenges Heat: Mechanistic Insights Into a Reaction Competing With Cadogan Cyclisation in Nitro‐Perylenediimides

Chemistry – A European Journal, EarlyView.
Visible‐light irradiation of nitro‐perylenediimide in the presence of triphenylphosphine reveals an unexpected pathway competing with the classical Cadogan cyclization. Mechanistic investigations uncover the rapid and selective formation of bay‐functionalized 1‐iminophosphorane‐12‐hydroxy perylenediimide derivatives.

Harnessing Acoustic Cavitation Energy for the Selective Degradation of Impurities in Glucose Syrup

Chemistry – A European Journal, EarlyView.
The energy released during the implosion of acoustic cavitation bubbles can be harnessed and selectively transferred to a target solute, enabling its specific decomposition without degrading other solutes present in the solution. This proof of concept was demonstrated in the degradation of impurities present in trace amount in glucose syrup.

Urothermal Synthesis of Luminescent Alkaline Earth MOFs

Chemistry – A European Journal, EarlyView.
The e‐murea derivative (1,3‐dimethylimidazolidin‐2‐one) was employed as solvent for the urothermal synthesis of a series of nine AE MOFs featuring luminescence in the crystalline state with remarkable quantum yields ranging from 0.45 to 0.84. ABSTRACT The urothermal approach in 1,3‐dimethylimidazolidin‐2‐one (e‐murea) was employed for the successful ...

The Future of Foundation Machine Learning Potentials and DFT in Homogeneous Catalysis: Competition or Synergy?

Chemistry – A European Journal, EarlyView.
Machine‐learning potentials are increasingly taking on the exploratory tasks of homogeneous catalysis, enabling rapid conformer sampling and reaction‐space mapping. However, when selectivity depends on subtle electronic effects, electronic‐structure methods remain essential.

Cationic Permethylated Cyclodextrins Capable of Self‐Assembling Into Linear Nanostructures in Water

Chemistry – A European Journal, EarlyView.
A quaternary ammonium bridge equipped with a lipophilic substituent in permethylated cyclodextrins suppresses undesired supramolecular interactions and promotes controlled, directional head‐to‐tail self‐assembly into well‐defined linear nanostructures.

Ligand‐Level Chemical Activation: Coordination with Benefits

European Journal of Inorganic Chemistry, EarlyView.
While often perceived as a liability, ligand‐based reactivity in carefully designed settings becomes a powerful synthetic tool. The key to streamlined processes overriding classical ionic reactivity is the selective electron redistribution induced by metal coordination. This enables storage of electrons and protons or incorporation of functional groups
