Altering the Coordination of Iron Porphyrins by Ionic Liquid Nanodomains in Mixed Solvent Systems [PDF]

, 2017
The solvent environment around iron porphyrin complexes was examined using mixed molecular/RTIL (room temperature ionic liquid) solutions. The formation of nanodomains in these solutions provides different solvation environments for substrates that could

f‐p‐d Gradient Orbital Coupling Induced Spin State Enhancement of Atomic Fe Sites for Efficient and Stable Oxygen Reduction Reaction

Advanced Functional Materials, EarlyView.
The f‐p‐d (Eu─O─Fe) gradient orbital coupling induces electron delocalization and the introduced f‐band of Eu shifts the spin state of the Fe center in FePc from low‐spin to intermediate‐spin. This strategy simultaneously enhances oxygen reduction reaction (ORR) activity, reaction kinetics, and stability, resulting in superior ORR performance and ...

Spectroelectrochemical Determination of Förster Radii for Triplet‐Polaron Quenching in Phosphorescent Organic Light‐Emitting Diodes

Advanced Functional Materials, EarlyView.
Phosphorescent OLEDs suffer from efficiency roll‐off due to triplet‐polaron quenching (TPQ). This study demonstrates for a large set of host‐guest combinations a spectroelectrochemical method to measure the absorption of charged molecules, enabling determining TPQ Förster radii (2.5–4 nm) from the spectral overlap.

Dynamic Networks via Polymerizable Deep Eutectic Monomers for Uniform Li+ Transport at Interfaces in Lithium Metal Batteries

Advanced Functional Materials, EarlyView.
The PDEM‐based SIGPE provides a dynamic nanophase from Li+‐bridged molecular self‐association, enhancing electrochemical stability and facilitating uniform Li+ ion flux at the interface. This unique solvation structure results in a hetero species‐driven inorganic‐rich SEI and long‐term cycle stability, suggesting that a PFAS‐free Li+‐containing monomer
