Photodynamic therapy (PDT) is a method that combines photosensitive drugs and laser activation to treat cancer. It has the advantages of minimally invasiveness, strong spatiotemporal controllability, small side effects, and low incidence of drug resistance. Traditional PDT uses light to excite a photosensitizer (PS) and transfer energy to oxygen to...

      Small molecule cyanine is a type of strong absorbing ligand with red or near-red light, which can red-shift the absorption intensity of molecules. It has important applications in the fields of synthetic ligands for metal complexes and intermediates for the synthesis of molecular probes. In addition, cyanine...

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...
