บทคัดย่อ

A new pyrenylbenzylidene-malononitrile (P2) was successfully synthesized via the Suzuki coupling reaction and Knoevenagel condensation using nano Cu as a catalyst. The compound P2 could detect hydrazine in 10% THF-PBS, pH 7.4, with a limit of detection (LOD) of 19.46 nM. Moreover, the P2-CA nanofibrous sheets were fabricated by combining compound P2 and cellulose acetate. The LOD of P2-CA nanofibrous sheets was found to be 0.02% w/v for hydrazine detection. The quantity of hydrazine vapor was recognized and quantified by analyzing fluorescence images acquired with a smartphone camera and a portable blacklight lamp that generates light with a wavelength of 365 nm using the ImageJ application. The concentration range of 0.025-1% w/v was accurately determined by employing ImageJ for fluorescence image analysis. Both compound P2 and P2-CA nanofibrous sheets are selective for hydrazine. Also, the mechanism of compound P2 and hydrazine was studied via1H NMR titration, FT-IR experiments and DFT calculations. In addition, the P2-CA nanofibrous sheet has the ability to detect hydrazine vapor in actual samples collected from the environment. Hence, the compound P2 and P2-CA nanofibrous sheets have significant promise as highly effective sensors for detecting hydrazine in water across many environments and industries. © 2024 The Royal Society of Chemistry.
