In this work, a novel fluorescent probe CDA, which was synthesized via a facile derivatization from natural and renewable camphor, exhibited aggregation-induced emission (AIE) characteristics in mixed aqueous media. The fluorescent aggregates showed an obviously enhanced fluorescence response toward N2H4. The response time of CDA aggregates for detecting N2H4 was within 20 s, and the detection limit was 2.26 ppb, which was far lower than the U.S. Environmental Protection Agency (EPA) standard (10 ppb). Moreover, probe CDA was also applied to detect gaseous and aqueous N2H4. Additionally, the cell imaging experiments demonstrated that probe CDA could be employed to visualize N2H4 in living organisms.
