“…The quenching efficiency, LOD and K SV are summarized in Table S10. Comparing the sensing performance of 4 a as multifunctional fluorescent probe towards NACs, these K SV and LOD possess certain advantage among the reported NACs probes [13,72,73] (For more detailed comparison, see Table S11). Therefore, 4 a can achieve the highly sensitive detection of NACs.…”

Six novel benzimidazole-based D-π-A compounds 4 a-4 f were concisely synthesized by attaching different donor/acceptor units to the skeleton of 1,3-bis(1H-benzimidazol-2-yl)benzene on its 5-position through an ethynyl link. Due to the twisted conformation and effective conjugation structure, these dual-state emission (DSE) molecules show intense and multifarious photoluminescence, and their fluorescence quantum yields in solution and solid state can be up to 96.16 and 69.82 %, respectively. Especially, for excellent photostability, obvious solvatofluorochromic and extraordinary wide range of solvent compatibility, DSE molecule 4 a is a multifunctional fluorescent probe for the visual detection of nitroaromatic compounds (NACs) with the limit of detection as low as 10 À 7 M. The quenching mechanism has been proved as the results of photoinduced electron transfer and fluorescence resonance energy transfer processes. Importantly, probe 4 a can sensitively detect NACs not only in real water samples, but also on 4 a-coated strips and 4 a@PBAT thin films.

“…Four polymeric TPEPs detected and distinguished nitroarenes by quenching their fluorescence in the aqueous phase with a K SV greater than 104 M −1 and a LOD below the ppm level for TNT [51]. More recently, two novel linear di(naphthalen-2-yl)-1,2-diphenylethene-based (DNDPE) conjugated polymers, P7-P8, were developed and studied (Figure 35) [52]. They possessed AEE activity due to the non-standard DNDPE-luminogen, good solubility, and high photostability.…”

Methods for the remote detection of warfare agents and explosives have been in high demand in recent times. Among the several detection methods, fluorescence methods appear to be more convenient due to their low cost, simple operation, fast response time, and naked-eye-visible sensory response. For fluorescence methods, a large variety of fluorescent materials, such as small-molecule-based fluorophores, aggregation-induced emission fluorophores/materials, and supramolecular systems, have been reported in the literature. Among them, fluorescent (bio)polymers/(bio)polymer-based materials have gained wide attention due to their excellent mechanical properties and sensory performance, their ability to recognize explosives via different sensing mechanisms and their combinations, and, finally, the so-called amplification of the sensory response. This review provides the most up-to-date data on the utilization of polymers and polymer-based materials for the detection of nitroaromatic compounds (NACs)/nitro-explosives (NEs) in the last decade. The literature data have been arranged depending on the polymer type and/or sensory mechanism.

“…In addition, it is also widely used for biomedical [ 25 ], environmental monitoring [ 26 ], food protection and quality control [ 27 , 28 ]. In this method, spectrofluorophotometer can generate the signal shift and be observed by the naked eye on-site [ 29 ]. Different types of recognition elements and materials have been used in the manufacturing of fluorescence sensors, including enzymes [ 30 ], semiconductor nanomaterials [ 31 ], metal nanomaterials [ 32 ], carbon materials [ 33 ] and noble metal [ 34 ], as it can enhance the sensitivity of the sensor.…”

Insecticides are enormously important to industry requirements and market demands in agriculture. Despite their usefulness, these insecticides can pose a dangerous risk to the safety of food, environment and all living things through various mechanisms of action. Concern about the environmental impact of repeated use of insecticides has prompted many researchers to develop rapid, economical, uncomplicated and user-friendly analytical method for the detection of insecticides. In this regards, optical sensors are considered as favorable methods for insecticides analysis because of their special features including rapid detection time, low cost, easy to use and high selectivity and sensitivity. In this review, current progresses of incorporation between recognition elements and optical sensors for insecticide detection are discussed and evaluated well, by categorizing it based on insecticide chemical classes, including the range of detection and limit of detection. Additionally, this review aims to provide powerful insights to researchers for the future development of optical sensors in the detection of insecticides.
