英文摘要: Fluorescent probes for hydrogen sulfide have received considerable attention because of the biological significance of H2S recognized recently. Two-photo microscopy offers advantages of increased penetration depth, localized excitation, and prolonged observation time. However, two-photon fluorescent probes for H2S are still rare. In this work, we introduced a dinitrophenyl ether group into the 4-position of 1,8-naphthalimide, which acts as the H2S reactive site, to efficiently yield compound NI-NHS as a two-photo fluorescent probe for H2S. The probe NI-NHS has a high selectivity for H2S over competitive anions and sulfide-containing analytes. This probe exhibits turn-on fluorescence detection of H2S in bovine serum and two-photon fluorescent imaging of H2S in living cells. (C) 2013 Elsevier Ltd. All rights reserved.
