Monosaccharide‐Based Macrocyclic Receptors—History and Recent Applications

Helvetica Chimica Acta, EarlyView.
This perspective provides an overview of most common applications of monosaccharide‐based macrocycles in molecular recognition over the past four decades. The most recent achievements, such as fluorescent ion sensing and selective amino acid binding in aqueous media, including the work from the author's lab, are highlighted. Potential future directions

Diterpenoid Diversity across Land Plants

Helvetica Chimica Acta, EarlyView.
Here we bridge the knowledge of diterpene chemical diversity, biosynthesis, and evolution from nonvascular mosses and liverworts to that known from vascular plants. ABSTRACT The diverse array of diterpenoid natural products stems from the ease of manipulating the promiscuity of diterpene cyclases.

Evaluation of Acephate Metabolites Generated by Zebrafish (Danio rerio) Using LC–HRMS and Metabolomics Approach

Journal of Applied Toxicology, EarlyView.
ABSTRACT Acephate is an organophosphate insecticide widely used. This pesticide can be metabolized into methamidophos, a molecule highly toxic. Both have demonstrated the ability to promote serious toxic effects on nontarget organisms and have been identified in surface waters around the world. Therefore, it is important to understand their behavior in

3D Polymeric Nanonetworks: From Self‐Assembly to Advanced Fabrication

Macromolecular Materials and Engineering, EarlyView.
This review provides the first systematic cross‐method comparison of fabrication techniques for 3D polymeric nanonetworks. It evaluates five key strategies—block copolymer self‐assembly, hyper‐crosslinking, template‐assisted methods, 3D printing, and nanolithography—across critical metrics including resolution, throughput, scalability, and material ...

Photoresponsive Metallo‐Supramolecular Systems Constructed From a Bidentate Ligand

Macromolecular Rapid Communications, EarlyView.
Metallosupramolecular polymer organogels based on dynamic metal–ligand (ML) cross‐links are rendered optically responsive by incorporating a photoacid generator. Exposing these systems to UV light releases an acid that protonates the ligands, causing network disassembly and thereby softening.
