Non-methane hydrocarbons (NMHCs) can serve as precursors of ozone and photochem. smog, and hence their highly efficient detection is of great importance for air quality monitoring. Here, we synthesized a new fluorescent perylene bisimide (PBI)-cored metallacycle complex through coordination-driven self-assembly and used it for the production of a fluorescent film sensor. The unique rectangular structure of the developed fluorophore endows the sensor with enhanced sensing performance and discriminability to n-alkanes (C5-10). Specifically, the exptl. detection limits for n-pentane, n-hexane, and n-decane are 39, 7, and 1.4 mg/m3, resp., and the corresponding linear ranges are from 39 to 2546, 7 to 1745, and 1.4 to 85 mg/m3, resp. Moreover, the sensing is fully reversible. In tandem with a gas chromatog. separation system, the film sensor showed comparable detection ability for the n-alkanes with a com. flame ionization detector (FID), while the film sensor needs no hydrogen; it occupies a much smaller size (30 x 30 x 44 mm3) and consumes less energy (0.215 W). Further studies demonstrated that the developed sensor can be used for on-site and real-time quantification of NHMCs, laying the foundation for developing into a portable detector. In addition to this study using 4-Ethynylpyridine, there are many other studies that have used 4-Ethynylpyridine(cas: 2510-22-7Application In Synthesis of 4-Ethynylpyridine) was used in this study.
4-Ethynylpyridine(cas: 2510-22-7) belongs to pyridine. Pyridines form stable salts with strong acids. Pyridine itself is often used to neutralize acid formed in a reaction and as a basic solvent. Application In Synthesis of 4-Ethynylpyridine
