Triptycene and its derivatives are a class of compounds with a unique three-dimensional rigid structure and are widely used in many fields such as molecular machines, materials chemistry, and supramolecular chemistry [1]. Researcher Chen Chuanfeng from the Institute of Chemistry, Chinese Academy of Sciences, successfully synthesized a new host molecule...

Metal-Organic Frameworks (MOFs): Revolutionizing Material Science Metal-organic frameworks (MOFs) are a rapidly developing class of coordination polymers. With their remarkable characteristics—structural diversity, porosity, tailorability, and high specific surface area—MOFs have become invaluable across various scientific and industrial fields. Applications include gas adsorption and storage, molecular separation, catalysis, drug sustained release,...

Understanding Pesticide-Related Impurities: Key to Safety and Quality Pesticide-related impurities refer to substances present in pesticide products that are more toxic to humans and the environment than their active ingredients. These impurities may harm crops, contaminate agricultural products, or adversely affect the stability and quality of pesticides. Monitoring such impurities...

Sulfur-containing compounds occupy a very important position in the fields of food science, life science, pharmaceutical science, and materials science. However, the synthesis of sulfur-containing compounds presents many challenges [1]:Traditional methods of preparing sulfur-containing compounds use mercaptans and thiophenols, which not only have an unpleasant odor, but also often deactivate...

Ligands can bond with metal central atoms through coordination or covalent bonds, directly affecting the chemical environment around metal atoms, thereby improving reaction conditions, catalytic activity and conversion rates. So far, scientists have developed Thousands of chiral ligands. Among them, chiral oxazoline ligands have the advantages of diverse structures, easy...

Chemical cross-linking coupled with mass spectrometry (CXMS) is widely used in protein interaction analysis, structure identification and kinetic studies. However, there are fewer types of cross-linking agents available for CXMS, which mainly target protein N-termini and lysine residues, resulting in limited structural information that this technology can provide.Arginine is abundant...
