✦ Synopsis

A naked-eye turn-on fluorescent Fe 3+ probe (RQ6) was developed by linking a new conjugated quinoline fluorescent group to the rhodamine platform. The probe can detect Fe 3+ with high selectivity over other metal ions. Bioimaging studies indicated that RQ6 was cell permeable and suitable for detecting Fe 3+ in the living cells by confocal microscopy.
