Tetraphenylethylene–thiosemicarbazone based ultrafast, highly sensitive detection of hypochlorite in aqueous environments and dairy products

Multiresponsive tetrarylethylene-based fluorescent dye with multicoloreded changes: AIEE properties, acidichromism, Al3+ recognition, and applications

“…The nonplanar structure that constitutes the propeller type ensured its strong fluorescence emission in the aggregation and solid state due to the restriction of intramolecular motions (RIMs). [14][15][16][17][18][19][20] For example, Wang et al explored a tetraphenylethene AIE fluorescent sensor, which is capable of visually distinguishing Th 4+ between lanthanide, transition metal, and alkali metal under UV light. 21 Lin et al developed a TPE-BSA sensor with good AIE features for uranyl ion detection by incorporating the salt benzene moiety into the active tetraphenylethene part of AIE.…”

Monitoring of Hypochlorite Level in Fruits, Vegetables, and Dairy Products: A BODIPY-Based Fluorescent Probe for the Rapid and Highly Selective Detection of Hypochlorite

“…Hypochlorite (ClO – ), which is a strong oxidizing agent, is widely used in food, vegetable, and dairy products to destroy microbial activity, delay food spoilage, and extend the shelf-life. , Additionally, because of its critical antimicrobial properties, ClO – is also used as a disinfectant for drinking water, wastewater, industrial waste treatment, and swimming pool treatment. − On the other hand, the acceptable chlorine level ranges from 50 to 200 mg/L for fruits and vegetables, excess amount of which could damage organs and tissues resulting in several diseases such as cardiovascular, neuron degeneration, kidney, arthritis, and cancer. − Therefore, development of a rapid and efficient method for the selective and sensitive determination of ClO – is in high demand. Compared to traditional methods, fluorescent probes have many advantages, such as sensitivity, selectivity, fast response, and real-time monitoring, thus garnering tremendous attention from researchers. − Although some fluorescent probes have been developed to detect ClO – , they have drawbacks, such as slow response, high detection limits, low quantum yields, turn-off response, cumbersome synthesis, and, especially, inability to be applied in actual food samples, which prompted us to develop a fluorescent probe with superior properties of selective and sensitive detection of ClO – to overcome such drawbacks. − …”

An Anthracene and Indole-based Fluorescent Probe for the Detection of Chromium(III) Ions in Real Water Samples

“…There are several instruments for detecting trace chromium(III) ions, including atomic absorption spectroscopy (AES), atomic emission spectroscopy (AAS), and inductively coupled plasma mass spectroscopy (ICP-MS) [14][15][16][17][18][19]. On the other hand, uorescence approaches have received much attention compared to the mentioned methods above because of their great sensitivity and selectivity, low cost, ease of operation, and real-time detection [20][21][22][23][24]. For the detection of chromium(III) ions, various uorescent probes have been developed, such as rhodamine [25][26][27], Bodipy [28,29], coumarine [30], and anthracene [31,32]based uorescent probes.…”
