Selective enclathration of picolines [PDF]

Acta Crystallographica Section A Foundations of Crystallography, 2004
The host 1,1,2,2-tetraphenyl-1,2-ethane diol has been employed to separate the isomers 2-picoline (2-pic), 3-picoline (3-pic), and 4-picoline (4-pic) by selective enclathration. The crystal structures are all stabilized by (host)-O−H···N(guest) hydrogen bonds. The competition experiments show that enclathration preferentially takes place in the order 4-

Dual‐Functional Sulfonated Nanocellulose for Proton Exchange Membranes With High Proton Conductivity at Low Humidity

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A scalable dual‐functional strategy yields simultaneously sulfonated and nanosized cellulose for proton exchange membranes with continuous hydrogen‐bond networks. These sustainable membranes exhibit low‐humidity proton conductivity twofold higher than Nafion 212, providing a robust solution for next‐generation fuel cells.

Chan–Lam Cross‐Coupling With Alkylboron Reagents: From Transmetallation to Radical Pathways

European Journal of Organic Chemistry, EarlyView.
Alkylative Chan–Lam coupling overcomes intrinsic transmetallation limitations of alkylboron reagents by engaging radical pathways. Recent advances reveal how radical and radical–polar crossover mechanisms enable mild C(sp3)—heteroatom bond formation. This minireview highlights key mechanistic insights and emerging strategies that transform alkylboron ...

Chemo‐Enzymatic Route for Covalent Cellulose Fiber Dyeing

Chemistry – A European Journal, Volume 32, Issue 14, 15 April 2026.
This work presents a proof of concept for a chemo‐enzymatic approach to the covalent dyeing of cotton fibers. Laccase/TEMPO oxidation introduces aldehyde groups, enabling subsequent reductive amination with amino dyes. Excellent color homogeneity and wash fastness were demonstrated using acid red 33, highlighting the robustness of the approach and its ...

Simplified Assembly Process for Efficient Light‐Driven MOF‐Based Water Oxidation Catalysts in Acidic pH

ChemPhotoChem, Volume 10, Issue 4, April 2026.
MOF based photoanodes for light driven water oxidation can be created by combination of Fe3O nodes in MOFs such as MIL101 and highly active Ru‐based single site water oxidation catalyst. Even with linker mismatch the MOF assembles and shows stable performance in photoelectrochemical water oxidation.

Synthesis and Biological Profile of Substituted Pyrrolidinyl Carboxamides for Acyl‐ACP Thioesterase Inhibition

European Journal of Organic Chemistry, Volume 29, Issue 12, 23 March 2026.
The work outlined herein covers a series of novel herbicidal lead structures that possess a pyrrolidinyl pyrazole carboxamide scaffold as a key structural feature, carrying further substituted benzyl side chains. Based on scaffold hopping approaches from known fungicidal and herbicidal compounds and utilizing an optimized synthetic approach, a broader ...

Direct‐to‐Biology: Streamlining the Path From Chemistry to Biology in Drug Discovery

ChemMedChem, Volume 21, Issue 4, 25 February 2026.
Crude yet clever: Direct‐to‐biology workflows exploit nanoscale synthesis and plate‐based assays to accelerate hit discovery, save precious intermediates, and rethink early drug discovery. Direct‐to‐biology (D2B) has emerged as a transformative concept in early drug discovery, defined by the direct on‐target screening of crude reaction mixtures without

Incorporating Heavy Atom Effect onto Molecular Rotors for Realizing Exceptionally Photocatalytic Oxidation Reaction under Low‐Temperature Conditions

Advanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
Here, we reported a series of molecular‐rotor‐based photoactivated oxidase mimics, DAPy‐Xm, in which heavy atom incorporation enhances both ROS generation and cold‐adapted property. Among them, DAPy‐Im enables efficient photo‐oxidation of ergosterol and photocatalytic H2O2 production at low temperature.
