4,4’-Dibenzoic acid is one of the important monomers for the synthesis of general-purpose high-performance polymers and liquid crystal materials. However, this monomer has shortcomings such as long industrial synthesis route, heavy pollution, low selectivity, and poor biodegradability of the synthesized polymer. Under increasingly severe environmental control and carbon neutrality restrictions,...

4,4’-Dibenzoic acid is one of the important monomers for the synthesis of general-purpose high-performance polymers and liquid crystal materials [1]. However, this monomer has shortcomings such as long industrial synthesis route, heavy pollution, low selectivity, and poor biodegradability of the synthesized polymer. Under increasingly severe environmental control and carbon neutrality...

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...

The disulfide skeleton containing two covalently linked sulfur atoms is an important molecular structure in life sciences, medical sciences, and food chemistry due to its unique pharmacological and physicochemical properties (Figure 1). For example, disulfide bonds in biomolecules play various roles in various biochemical redox processes; the secondary and tertiary...

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...
