摘要:
Herein, a novel two-photon excited fluorescent sensor for the detection of zinc ions in aqueous solution as well as in cells was synthesized by the complexation process using an aggregation-induced emission (AIE) fluorophore. The near-infrared AIEgen chemosensor containing Schiff base derivatives with a salicylaldehyde moiety showed a distinctly selective response to zinc ion. The tetraphenylethylene quinoline benserazide probe based on tetraphenylethylene structure complexed zinc ions and then aggregated in aqueous buffered solution, causing t...
