High-fidelity in vivo fluorescence monitoring of physiological processes is crucial in disease diagnosis and biological research, but it faces extreme challenges due to aggregation-induced quenching (ACQ) and short-wavelength fluorescence. The development of high-performance, long-wavelength aggregation-induced emission (AIE) fluorophores has placed higher demands on precise optical bioimaging.Chromophore-quinoline-malononitrile (quinolinenitrile, QM) is a...
