“…In another example, Chatterjee and co‐workers have synthesized a novel AIE‐based fluorescent probe for the detection of trace number of nitrites and nitrate ions in water. [61] The probe was synthesized by McMurry coupling reaction. The synthesized probe undergoes diazotization by reaction with NO 2 − ion followed by coupling with β‐naphthol to produce azodye.…”

The major findings in the growing field of aggregation induced emissive (AIE) active materials for the detection of environmental toxic pollutants have been summarized and discussed in this Review article. Owing to the underlying photophysical phenomenon, fluorescent AIE active molecules show more impact on sensing applications. The major focus in current research efforts is on the development of AIE active materials such as TPE based organic fluorescent molecules, metal organic framework, and polymers that can be employed for the detection of toxic pollutants such as CN − , NO 2 − , Hg 2+ , Cd 2+ , As 3+ , As 5+ , F − , Pb 2+ , Sb 3+ ions.

“…Diazothization reaction can be used for detection of nitrite. For example, Banerjee reported an AIE-based nitrite chemosensors in which amino-TPE ( E3 ) was converted to into its diazonium salt followed by coupling with β-naphthol (Scheme 10) [118]. During this process, blue fluorescence of E3 was quenched as the TPE-azo-naphthol compound is non-fluorescent [118].…”

Recent Advances in Aggregation-Induced Emission Chemosensors for Anion Sensing

The discovery of the aggregation-induced emission (AIE) phenomenon in the early 2000s not only has overcome persistent challenges caused by traditional aggregation-caused quenching (ACQ), but also has brought about new opportunities for the development of useful functional molecules. Through the years, AIE luminogens (AIEgens) have been widely studied for applications in the areas of biomedical and biological sensing, chemosensing, optoelectronics, and stimuli responsive materials. Particularly in the application of chemosensing, a myriad of novel AIE-based sensors has been developed to detect different neutral molecular, cationic and anionic species, with a rapid detection time, high sensitivity and high selectivity by monitoring fluorescence changes. This review thus summarises the recent development of AIE-based chemosensors for the detection of anionic species, including halides and halide-containing anions, cyanides, and sulphur-, phosphorus- and nitrogen- containing anions, as well as a few other anionic species, such as citrate, lactate and anionic surfactants.

“…Practically, the probe was synthesized in a single step by 100% atom-economic way from a known TPE-derivative (TPE-NH 2 ). First, TPE-NH 2 was synthesized from benzophenone and 4-aminobenzophenone by McMurry cross-coupling and characterized (see ESI for details †) 44. The TPE-NH 2 was converted to TPE-PMI using a mechanochemical method by milling of TPE-NH 2 and phthalic anhydride under neat condition followed by heating at 230 C in a Teon container resulting in the formation of TPE-PMI in high yield.…”
