Benzylic Oxidation of Pillar[5]Arene: From Homo‐ to Cross‐Conjugated Macrocyclic Systems

Chemistry – A European Journal, EarlyView.
Selective benzylic oxidations of pillar[5]arene have been carried out to generate all the possible oxidized derivatives containing from one up to five carbonyl subunits. Effects resulting from the homo‐ and the cross‐conjugation within this series of compounds have been investigated in details and analyzed with the help of DFT calculations.

Xylose Acetals ‐ a New Class of Sustainable Solvents and Their Application in Enzymatic Polycondensation

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...

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

EcoEnergy, 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 ...

Ullmann‐Type N‐Heteroarylation of Nitrogen Heterocycles Catalyzed by Heterogeneous CuNPs/HKUST‐1

EcoEnergy, EarlyView.
A practical strategy for the direct synthesis of CuNPs/HKUST‐1 heterogeneous catalyst was developed and used for the catalyzing Ullmann‐type N‐arylation of N‐heterocycles with high yields, excellent recyclability, and low copper leaching. ABSTRACT Ullmann‐type C–N coupling is an essential reaction to construct functional nitrogen heterocycles, whereas ...

Synergistic‐Induced Perovskite Phase Distribution and Lattice Stabilization for Efficient and Stable Sky‐Blue PeLEDs

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We have developed a multifunctional buried‐interface engineering strategy using phenethylammonium thiocyanate to regulate quasi‐2D perovskite crystallization and stabilize the lattice. The synergistic effects of SCN− and PEA+ steric confinement promote phase redistribution toward n = 2, suppressing interfacial defects and enabling the production of ...

Managing Crystallization in Tin‐Lead Perovskite Solar Cells via Differential Chelating Coordination

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A chelation‐mediated crystallization strategy is developed for Sn–Pb perovskites using 1,10‐phenanthroline. Stronger coordination with Sn than Pb helps reconcile their mismatched crystallization behavior, leading to improved crystalline quality, fewer defects, and reduced oxidation.

Three Birds with One Stone: High‐Performance 2D Lead‐Free Perovskite Solar Cells via Direct In Situ Generation of Organic‐Spacer Precursors

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Adopting a “three birds with one stone” strategy, the in situ generation of organic spacer simultaneously addresses three major challenges limiting 2D tin‐based perovskites: (1) Sn2+ oxidation; (2) rapid crystallization; and (3) uncontrolled 2D phase distribution.

Axial Chirality Control Through Palladium‐Catalyzed Alkenylation Reactions for the Atroposelective Synthesis of 4‐Arylquinolin‐2‐ones

European Journal of Organic Chemistry, EarlyView.
Palladium(II)‐catalyzed intramolecular C─H alkenylation of cinnamides allows the atroposelective synthesis of axially chiral 4‐arylquinolones, with the chirality being installed by ring formation. DFT studies have shown that the reaction proceeds by prior activation of the alkene and the enantioselectivity is determined during the β‐hydride elimination

Toxicity and toxicokinetics for benthic organisms: I: Toxicity and BCF values of chlorobenzenes to Chironomus riparius in water only experiments

, 2012
niet beschikbaarThis report is the first in a series to support the so called porewater hypothesis which is used to derive sediment quality criteria. The porewater hypothesis assumes that toxicity to benthic organisms is caused by the soluble fraction of
