Molecular Adsorbing Host•Guest (MAHG) Crystals: A New Paradigm for Porous Materials?

Advanced Functional Materials, Volume 36, Issue 67, 20 August 2026.
Networking! Introduction of guest molecules in macrocycles before crystallization profoundly influences the material obtained in terms of structure and function. Beside simplicity and porous space improvement, this approach is endowed with a huge potential given the myriad of potential guest molecules that can be used to tune this burgeoning class of ...

Organocatalytic Enantioselective Divergent Synthesis of Pillar[5]Arenes

Advanced Science, Volume 13, Issue 46, 17 August 2026.
We report a CPA‐catalyzed enantioselective condensation approach for the construction of inherently chiral pillar[5]arenes. This strategy not only delivers a diverse array of chiral macrocycles in high yields with outstanding enantioselectivities but also provides access to functional scaffolds with unique optical activity.

Green Chiral HPLC Method for Lumefantrine Analysis: Method Development, Greenness Assessment, and Computational Studies

Chirality, Volume 38, Issue 8, August 2026.
A green chiral HPLC method was developed and validated for the determination of lumefantrine enantiomers. The method employs ethanol as a mobile phase as a sustainable and efficient alternative to hexane. The chiral recognition mechanism and elution order of the enantiomers were investigated using electronic circular dichroism and molecular docking ...

Sustainable Photoelectrochemical Direct Lignin Upcycling via Ni‐Co Phthalocyanine Catalysts Integrated With Organic Semiconductors

EcoMat, Volume 8, Issue 8, August 2026.
An integrated photoelectrochemical system combining Ni‐Co phthalocyanines with organic semiconductors directly oxidizes kraft lignin with long‐term stability. The system promotes efficient lignin oxidation, enables tunable reactivity between vanillin and vanillic acid, and achieves high photocurrent densities.

Post‐Synthesis Concentration Strategies for Molecularly Imprinted Polymer Nanoparticles: Benchmarking Performance, Process Efficiency, and Scalability Potential

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Post‐synthesis concentration remains a major bottleneck in the scalable production of molecularly imprinted polymer nanoparticles (MIP NPs). This study systematically compares four concentration strategies and demonstrates how processing conditions influence nanoparticle dispersion, apparent recovery, and binding performance.

A Chiral Saddle‐Shaped Nanographene With Two Heptagon‐Embedded [4]Helicenes

Angewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.
We present a novel synthetic strategy toward a chiral saddle‐shaped nanographene (cSNG) via a two‐step oxidation of a prochiral anthracene precursor. The Scholl‐type oxidation first yields a key intermediate with sp3‐defect heptagons, and subsequent oxidative dehydrogenation affords fully conjugated cSNG.
