摘要
2,7-BHVC,a novel two-photon fluorescent probe for DNA with large two-photon excited fluorescence action cross sections,was synthesized and characterized.It emits weak two-photon fluorescence in aqueous solution while its two-photon fluorescence is strongly restored upon binding to DNA.The two-photon imaging in cell demonstrated that 2,7-BHVC can exactly label nuclear DNA.
