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 ''turnoff'' 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.

“…Efficient molecular design and synthesis of novel fluorescent organic small molecules have attracted significant attention among the researchers for their promising applications in the field of fluorescent molecular probes, bioimaging, light-emitting electro-chemical cells, chemosensors, photovoltaics, and solid-state lighting. [1][2][3][4][5][6][7][8][9][10] Precise bandgap engineering of an organic molecule achieved by various chemical routes has proven successful in the generation of desired fluorescent color emission. Design strategies of active light emitters must result in the system possessing an optimal highest occupied and lowest unoccupied orbital energy levels to ease the charge injection and transport into the emissive layer.…”

Schiff's base condensation of 4,5-Dimethyl-1,2-phenylenediamine with various aldehydes namely fluorene-2-carboxaldehyde (MBF), N-ethyl-3-carboxaldehyde (MBE), 8-hydroxyjulolidine-9-carboxaldehyde (MBJ) and N-(4-formylphenyl) carbazole (MBB) functioning as light emitters have been synthesized. Solid-state emission reveals the exhibition of variant fluorescent color achieved by mere variation in the peripheral group attached to the core. Amongst the designed system, MBB showed a solid-state blue light emission with its emission peak centered at 453 nm. The fluorescence quantum yield of MBB displayed value of 44.82% in the solution state. Electrochemical studies on MBB estimated a HOMO energy level at À 5.7 eV and LUMO at À 3.2 eV. OLED realized with MBB as an active emitter material was successful in the generation of bluish-green emission with a maximum brightness of 280 cd/m 2 . Current efficiency of 2 cd/A and a power efficiency of 0.18 lm/W was observed for the fabricated device.[a] M. Mohan, S. M. Nagarajan

“…Up to now, several film sensors based on AIE-ICT fluorophores have been reported for the consideration of portable detection of gaseous amines, nitroaromatic compounds, acids, water, and other analytes in the air. − The fluorophores were adopted as sensing units because they are believed to possess advantages of higher emission efficiency, multicolor response, and moderate sensitivity. However, performance of the films is not as good as expected.…”

Film-based fluorescence sensing is recognized as one of the most optimized techniques for trace analysis of chemicals in the air after the invention of ion mobility spectrometry. The performance of the technique is highly dependent on the design of the film. This paper reports a new fluorescent film which shows unprecedented and discriminative sensing performance to the presence of phenol, o-cresol, m-cresol, and p-cresol in the air with an ultralow detection limit as low as 0.4, 0.3, 10, and 0.8 ppt, respectively. The film was designed via combination of the advantages of aggregation-induced emission (AIE) and those of intramolecular charge transfer (ICT), where the former provides the opportunity to avoid the widely encountered aggregation-caused quenching (ACQ) effect and the latter allows sensitive sensing of the microenvironment change of the film. The biggest challenge of the design is to find a fluorophore possessing both AIE and ICT effects. Fortunately, a newly synthesized biphenyl derivative of o-carborane capped with azetidine moiety (BZPCarb) shows the properties as expected. Importantly, the fluorophore is photochemically stable, a prerequirement for multiple uses of a film device. In addition, the nonplanar structure of the fluorophore is also favorable for film sensing as it could form porous films owing to screening of dense stacking of the molecules. It is the merits that make BZPCarb-based film show outstanding sensing and discriminative performances. Based on the fluorophore and the design, a conceptual high-performance fluorescent vapor sensor for phenolic compounds was developed.
