A naked-eye turn-on fluorescent Fe3+ probe (RQ6) was developed by linking a new conjugated quinoline fluorescent group to the rhodamine platform. The probe can detect Fe3+ with high selectivity over other metal ions. Bioimaging studies indicated that RQ6 was cell permeable and suitable for detecting Fe3+ in the living cells by confocal microscopy.
6-Substituted quinoline-based ratiometric two-photon fluorescent probes for biological Zn2+ detection

New ratiometric two-photon fluorescent probes are developed from 6-substituted quinolines for biological Zn2+ detection. They show large red shifts and good ratiometric responses upon Zn2+ binding. They also exhibit high ion selectivities and large two-photon absorption cross sections at nearly 720 nm. Because the new probes are cell-permeable, they can be used to detect intracellular zinc flux under two-photon excitation.
