A linear bisphenanthroline (two binding sites) is set up to operate as a XNOR gate and a linear trisphenanthroline (three binding sites) as a molecular 3-input ANDâNORâOR logic circuit, both with H+ as input signal and luminescence as output signal.

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.
