A novel ratiometric dehydroabietic acid-based fluorescent probe for detecting HPO42- and its application in food samples

Small-molecule fluorogenic probes based on indole scaffold

“…Phosphate ions are one of the most important anions in biological processes such as gene regulation and cell signaling, and also play important roles in industry. 46 They have many uses in food industries; phosphates enhance the water-holding capacity of meat and seafood products, and also improve the fluidity and flavors of milk. However excessive accumulation of phosphate ions may cause diseases like hyperphosphatemia, renal dysfunction, cardiovascular problems, osteomalacia, etc .…”

Multi-site isomerization of synergistically regulated stimuli-responsive AIE materials toward multi-level decryption

“…Stimuli-responsive optical materials can be viewed as materials that produce corresponding light signals in the presence of external stimuli such as light, 1–6 mechanical force, 7–9 pH changes, 10–12 ions, 13–19 etc. Due to their advantages of high sensitivity, fast response, and real-time visualization of light signals, the development of “intelligent” stimuli-responsive optical materials has attracted significant interest.…”

Fabrication of efficient and red-emissive salicylaldehyde Schiff base isomers for multi-scenario information decryption

“…Stimuli-responsive fluorescent materials (SRFMs) are smart materials that can alter fluorescence signals in response to external stimuli, including light, 1,2 mechanical force, 3–5 temperature, 6,7 and pH. 8–10 Due to their vast potential applications in anti-counterfeiting, 11,12 information encryption–decryption, 13,14 biochemical sensors, 15–18 and optoelectronic devices, 19,20 the development of SRFMs has gained significant attention in recent years. 21 Hence, many conventional stimuli-responsive molecular scaffolds, such as spiropyran, 22,23 azobenzenes, 24,25 dihydroazulenes, 26,27 diarylethenes, 28,29 and Schiff bases, 30,31 have been developed with dynamic covalent bonds for advanced applications.…”
