The shielded linear trisphenanthroline 1 is utilized as a triple reassurance probe and as an ON–OFF–ON signaling unit (after addition of Cu2+) for the detection and quantification of Cr3+ ions. The analogous monophenanthroline 2 served as a ratiometric fluorescent chemosensor for analyzing the Cr3+/Cr2+ ratio.
