🔬 Background & Molecular Design Aggregation-induced emission (AIE) is a photophysical phenomenon in which certain fluorogens emit weak or no fluorescence in solution but exhibit significantly enhanced fluorescence in the aggregated or solid state. In recent years, AIE molecules have gained increasing attention in biomedical imaging. TriPEX is a class...

Benthio Green—A DNA Fluorescent Dye with Large Stokes Shift and Low Toxicity A large Stokes shift (Δλ > 120 nm) reduces spectral crosstalk between excitation and emission, improving the signal-to-background ratio and facilitating high-resolution fluorescence imaging, which is particularly important for high-performance fluorescent dyes.The research team led by Professor Zhou...

Technical Upgrade To overcome the limitations of traditional cell membrane dyes in imaging persistence, Professor Qian Zhaosheng’s research team recently developed the FM 2.0 fluorescent dye series. This new generation of dyes achieves comprehensive upgrades based on FM 1.0 technology! Not only does it extend imaging time to over 2-6...

Aggregation-induced emission (AIE) materials are currently the only new class of materials pioneered by Chinese scientists, originating from the work of Academician Benzhong Tang. Recognized by the International Union of Pure and Applied Chemistry as one of the "Top Ten Emerging Technologies in Chemistry Worldwide," AIE demonstrates unique optical properties...

Emerging Potential of Coinage‑Metal TADF Complexes In recent years, a series of two‑coordinate complexes based on coinage metals (copper, silver, and gold) have emerged as a new class of thermally activated delayed fluorescence (TADF) emitters, demonstrating great potential in photoluminescence mechanism studies, electroluminescent devices, photocatalysis, and other fields. Breakthrough in...

1.Definition and Reactivity of Benzyne Benzyne, also known as dehydrobenzene, refers to a structure formed by the removal of two hydrogen atoms from an unsaturated benzene ring, resulting in a formal carbon-carbon triple bond. Due to its highly strained formal triple bond structure, benzyne enables one-step ortho-difunctionalization of the benzene...
