A highly selective Al 3+ ‐morpholine anthracene ( 1 • Al 3+ ) chelate was designed as a novel fluorescent photonic switch for H 2 PO 4 − and CN − ions. The in situ ‐generated Al 3+ chelate could be used to detect H 2 PO 4 − ions only in the absence of CN − ions. In contrast, CN − ions effectively extruded Al 3+ from the chelate, resulting in the regeneration of probe 1 with a concomitant revival of PET, resulting in a turn‐off response. By exploiting the complexation‐ and decomplexation‐aided off–on switching system through the sequential addition of Al 3+ followed by H 2 PO 4 − or CN − , combinational photonic logic circuits, as well as image‐guided fluorogenic tracking, was demonstrated.
