A red-NIR fluorescent probe for rapid and visual detection of acrolein

Abstract: A novel red-NIR probe (SWJT-8) for detecting acrolein by utilizing Michael addition reaction was developed. SWJT-8 exhibits a series of unique advantages, such as colorimetric discrimination, high selectivity and fastest...

“…In connection with our previous work [ 26 , 48 , 49 ], herein, we reported a novel chemodosimeter ( SWJT-9 ), which had a large Stokes shift and emitted near-infrared fluorescence due to using a dicyanoisophorone skeleton. It can specifically recognize a hypochlorite anion based on the inhibition of C=N rotational isomerization [ 50 ].…”

“…Compound 2 (5.01 g, 15.61 mmol) and hexamethylenetetramine (4.16 g, 29.65 mmol) were dissolved in trifluoroacetic acid (20 mL), heated to 100 °C, and reacted for 8 h. The mixture solution was cooled to room temperature and extracted with CH 2 Cl 2 (2 × 150 mL). Finally, the collected organic layers were concentrated and purified by column chromatography (petroleum ether:ethyl acetate = 4:1) on silica gel to obtain the known compound 3 [ 49 ] (1.80 g, 33.1%).…”

“…Then, the probe SWJT-20 was designed using isophorone as the fluorophore and the hydroxyl group as a recognition site ( Scheme 1 ), which was synthesized by compound 2 [ 50 ]. In addition, an aldehyde group was introduced into the ortho position of hydroxyl group in compound 2 by Duff reaction [ 51 ] to obtain SWJT-20 [ 52 ], which was characterized using 1 H, 13 C NMR spectra, and HRMS ( Figures S1–S3, Supplementary Materials ). The aldehyde group will form an intramolecular hydrogen bond with the ortho hydroxyl group, which expands the conjugation of the probe.…”

“…In connection with our continuing study on chemodosimeters for the detection of biological species, [36][37][38][39][40] herein we design and synthesize a novel ratiometric fluorescent probe SWJT-10 to detect FA with an extremely fast response time (less than 5 s), high sensitivity, high selectivity and less background interference. And SWJT-10 has been successfully applied to detect FA in vitro and in vivo.…”
