Dual-mode recognition of biogenic amine tryptamine and fluoride ions by a naphthyl hydrazone platform: application in fluorescence imaging of HeLa cells and zebrafish embryos

A new type of selective and sensitive naphthyl hydrazone anchored Schiff base derivative ( PYNA ) was synthesized and applied to the fluorogenic and chromogenic recognition of both tryptamine ( TryptA ) and F − ions, further it has good cell permeability and biocompatibility in zebrafish embryos and HeLa cells.
