Herein, we have designed and synthesized new diimino dicarbazole derivative 3 which exhibits the phenomenon of aggregation induced emission enhancement (AIEE) due to the persistence of excited state intramolecular proton transfer (ESIPT) phenomenon. The aggregates of AIEE active material 3 selectively sense Cu2+ ions in nanomolar range and mediate the conversion of Cu2+ ions to Cu nanorods. The ensemble of aggregates of 3 and Cu nanorods were further utilized for selective sensing of CN¯ ions. In addition, the fluorescence behavior of the system generates the formation of molecular keypad security device. The keypad security device based on AIEE material adds to complexity of the lock and makes it more efficient.
