摘要：
A novel multifunctional probe, L, based on triphenylamine o-hydroxyl Schiff base was constructed for the sequential detection of Zn2+/P2O74-. Interestingly, probe L also showed two-photon fluorescent "off-on" response to Zn2+ along with a large effective two-photon absorption cross-section value of 240 GM at 720 nm, a low cytotoxic and a moderate photostability, which made L a good candidate for two-photon fluorescence microscopy imaging and monitoring the fluctuation of exogenous Zn2+.
