文摘

For the first time, a new near-IR 鈥渢urn-on鈥?fluorescent chemosensor with high selectivity for Hg²⁺ ions was designed according to the twisted intramolecular charge transfer (TICT) mechanism. The selective fluorescence enhancement effect can be optimized by modulating the solvent systems. And this naphthalenedimide-based sensor with long wavelength absorption and emission can be used to image intracellular Hg²⁺ ions in living Hela cells.
