The Zhang Xiaobing-Yuan Lin research group at Hunan University has developed a novel single-benzene-based fluorescent dye (SBFs) (Figure 1). This dye offers universal emission wavelength tunability, covering the entire visible spectrum in both solutions and solid states 1. By overcoming the strong intramolecular and intermolecular hydrogen bonding limitations of most...

DQF Fluorescent Dye – A Rhodamine-Based Dye with Large Stokes Shift Organic small-molecule fluorescent dyes have been widely applied in functional molecular labeling and detection, offering real-time, in-situ visualization for various biomedical research applications. However, most commonly used fluorescent dyes—such as fluorescein, rhodamine, oxazine, and cyanine—suffer from small Stokes shifts...

Metal-organic frameworks (MOFs) are crystalline porous materials with a periodic network structure, formed through the self-assembly of inorganic metal centers (metal ions or metal clusters) and bridging organic ligands. Due to their structural diversity, high porosity, and large specific surface area, MOFs hold immense potential across various research fields, including...

γ-Ketosulfones are crucial building blocks in medicinal chemistry, serving as key bioactive components in antibacterial, anticoagulant, and antitumor drugs. However, traditional synthesis methods typically involve: Oxidation of γ-ketothioethers: Requires strong oxidants and harsh conditions. Derivatization of sulfinates: Involves cumbersome, multi-step processes. These limitations hinder broader applications, making it difficult to...

Sulfones are widely found in biomolecules and pharmaceuticals, serving as essential building blocks in synthetic chemistry. Similarly, the trifluoromethylthio (-SCF₃) group plays a crucial role in drug design and synthesis due to its strong electron-withdrawing properties. Professor Lian Zhong from Sichuan University has developed a Cu-catalyzed multicomponent reaction that enables...
