Aggregation-Induced Emission: A Tool for Sensitive Detection of Amines

The aggregation-induced emission (AIE) phenomenon has shown great potential to develop sensors for amine detection. The AIE-active fluorescent probes are free from the aggregation-caused fluorescence quenching, which is a major problem in the conventional fluorescent probes. The fluorescent aggregates formed by AIE strategy offer advantages such as high selectivity, sensitivity, low background interference as well as the simplicity of the fluorescence technique. This review aims to highlight the recent developments of AIE-active probes for the detection of amine derivatives. We will focus our discussion on the AIE concept to develop ''turn on'' and ''turn-off'' fluorescent sensors for the detection of amine derivatives. Thereafter, we will discuss the various examples of amine sensor with their detection mechanism. Finally, we will give a future perspective for the development of AIE-based amine sensors. We believe, this review will inspire scientists of this emerging world for the development of new amine sensors.
