A fast-responsive two-photon fluorescent probe for detecting palladium(0) with a large turn-on fluorescence signal

摘要

A new two-photon fluorescent probe based on the GCTPOC two-photon fluorescent dye is designed and synthesized for detecting palladium(0) with fast response (6 min). And ideal properties including good selectivity, high sensitivity and low cytotoxicity are depicted. A 130-fold fluorescence enhancement was obtained. The new GCTPOC-Pd(0) probe could be employed to image Pd(0) in living cells and tissues with significant fluorescence emerging up to 170 mu m by the way of two-photon fluorescence microscopy.
