Quantum Chemistry Investigation of Linear and Nonlinear (chir)optical Properties of Oligoamide Foldamers

open access: yesChemistryEurope, EarlyView.
The linear and nonlinear (chir)optical properties of four oligoamide foldamers with different donor groups are studied by means of time‐dependent density functional theory calculations. It is shown that stronger donors yield larger hyperpolarizabilities due to low‐lying charge–transfer states. The agreement with the experiments concerning the key bands

Keggin‐Type Aluminum Polyoxometalate‐Mediated Oxidation of Amorphous Carbon for Engineered Electrochemical Interfaces

open access: yesCarbon Energy, EarlyView.
Keggin‐type Al‐POM‐coated silica achieves selective surface oxidation of amorphous carbon through electrostatic attraction and proton‐coupled oxidation, tailoring interfacial properties for lithium‐ion batteries and semiconductor processes. ABSTRACT Amorphous carbon is widely used in energy storage and semiconductor technologies, where surface ...

Synergistic Fe–Si Dual‐Site Pathway Engineering in Biomass‐Derived Carbon Matrix for High‐Performance Oxygen Reduction Reaction

open access: yesCarbon Energy, EarlyView.
We report a dual‐atomic Si–Fe–N–C catalyst synthesized from nitrogen‐rich pinecones and an Fe porphyrin precursor. The inherent Si and N in pinecones form a porous Si–N–C framework that stabilizes Fe atoms during pyrolysis, yielding robust Si–Fe dual sites.

Dipolar Molecular Motor Candidates with Planar Chirality

open access: yesChemistry – A European Journal, EarlyView.
Two prototypes of molecular motors with simultaneous implementation of planar chirality and a permanent dipole have been designed and synthesized in 7 steps with overall yields of 2.8 to 5.5%. Abstract Two molecular motor candidates built around ruthenium(II) centers featuring both planar chirality and a permanent dipole have been synthesized in seven ...
