Aggregation induced emission based fluorenes as dual-channel fluorescent probes for rapid detection of cyanide: applications of smartphones and logic gates.

ABSTRACT: Rational modification of molecular structure by incorporating electron donating groups can play a potential role for designing aggregation induced emission (AIE) active fluorescent probes. Based on this principle, fluorescent probes (1a-c) were synthesized, and they displayed excellent aggregation induced emission (AIE) behavior in a H₂O/DMF (4 : 1, v/v) mixture due to restrictions in intramolecular charge transfer (ICT). As a comparison, probe 1d was synthesized by installing an electron withdrawing (-NO₂) group that surprisingly quenched the aggregation behaviour. Additionally, AIE active probes 1a-c displayed a highly sensitive dual channel (fluorometric and colorimetric) response towards rapid detection of CN^-, which is an active toxic mat
