“…Based on previous works in our group, and other thiol‐ based fluorescent probes reported, one simple procedure was proposed to synthesize APTC with simple structure via Suzuki coupling reaction by combining 2‐phenyl‐1,2,3‐triazole with an anthracene group. The fluorescence characteristics was studied.…”

Summary of main observation and conclusion In this work, a new simple and readily synthesized turn‐on probe 2‐(4‐anthracene‐9‐yl‐phenyl)‐ 2H‐[1,2,3]triazole‐4‐carbaldehyde (APTC) was legitimately designed towards homocysteine (Hcy). Moreover, APTC has excellent optical properties such as intramolecular charge transfer (ICT) and aggregation induced emission enhancement (AIEE) characteristics, indicating its extensive application potentiality. What's more, APTC displayed rapid, high selectivity and specificity towards homocysteine over cysteine/glutathione. The detection limit of APTC for Hcy was as low as 2.198×10–8 mol·L–1, and the response time was only 5 min. APTC has been successfully applied to detect Hcy in silica gel plates and living cells, which indicates that APTC has good stability and biocompatibility as a selective probe for Hcy. Finally, the mechanism was studied using 1H NMR titration experiments and mass spectrometry.

“…Mohr [9] and Wei et al [10] have developed a colorimetric method to detect formaldehyde, but this method has a lack of sensitivity. Meanwhile, fluorometric [11][12][13][14][15][16][17] has advantages over other methods, namely simpler, faster, cheaper, a great sensitivity, and it can be used for routine analysis [18][19][20].…”

Compound of 3,3'-(4-(2-amino-4,5-dimethoxyphenyl)pyridine-2,6-diyl)dianiline (CHP) has been synthesized via three-step synthetic procedure from veratraldehyde as starting material and 4-(4,5-dimethoxy-2-nitrophenyl)-2,6-bis(3-nitrophenyl)pyridine (CHP-1) as an intermediate compound. The CHP-1 was reduced using hydrazine hydrate catalyzed by 10% Pd/C to the final target of CHP. The spectroscopic study revealed that CHP in acetonitrile could detect formaldehyde through fluorescence enhancement and showed color change from yellow to blue under the 365 nm portable ultraviolet lamp as a response. Based on the fluorescence spectra, the emission wavelength of CHP in acetonitrile was shifted from 526 to 480 nm after addition of formaldehyde. Limit detection (LOD), selectivity, sensitivity, and computational study geometry of CHP as a chemosensor for formaldehyde has also been investigated. CHP could also be applied as a test paper for the detection of formaldehyde qualitatively.

“…Spectrophotometric methods in detection of formaldehyde are divided into colorimetric (Mohr 2003;Wei et al 2019) and fluorometric (Bi et al 2018;Dong et al 2016;He et al 2016;Hidayah et al 2019;Liu et al 2015;Ovianto et al 2017;Roth et al 2015;Song et al 2012;Wu et al 2018;Xu et al 2016;Zhang et al 2018;Zhou et al 2018Zhou et al , 2015. The method has advantages over other methods, namely simpler, easier to handle, cheaper, higher in sensitivity and can be used for routine analysis (Chen et al 2015;Indang et al 2009;).…”

Azine derivative 6,6'-((1E,1'E)-hydrazine-1,2-diylidenebis(methanyly-lidene))bis (3,4-dimethoxy-aniline) CHA has been synthesized by condensation of 6-nitroveratraldehyde with malononitrile followed by reduction using 10% Pd/C and hydrazine hydrate. In the presence of formaldehyde, CHA chemosensor in ethanol showed a yellow-to-red color change observable by the naked eyes and 'turn off' type fluorescence quenching in ethanol. This phenomenon was confirmed by UV-Vis, fluorescence and 1 H NMR spectroscopy. The CHA spectra in ethanol was shifted from 412 to 509 nm after addition of formaldehyde. Fluorescence intensity of CHA gradually decreased with the increase of formaldehyde concentrations. Furthermore, paper strips loaded-CHA were fabricated and served to detect formaldehyde qualitatively. The detection limit of the CHA probe to formaldehyde is 0.2 M. ABSTRAKTerbitan azina CHA 6,6'-((1E,1'E)-hidrazina-1,2-diilidenebis(metanili-liden))bis (3,4-dimetoksi-anilin) telah disintesis dengan pemeluwapan 6-nitroveratraldehid dengan malononitril diikuti dengan pengurangan menggunakan 10% Pd/C dan hidrat hidrazina. Dengan kehadiran formaldehid, kemoderia CHA dalam etanol menunjukkan perubahan warna daripada kuning kepada merah yang boleh diperhatikan oleh mata kasar dan 'mematikan' jenis pemelindapan kependarfluoran dalam etanol. Fenomena ini disahkan oleh UV-vis, kependarfluoran dan spektroskopi 1 H NMR. Spektrum CHA dalam etanol telah beralih daripada 412 kepada 509 nm selepas penambahan formaldehid. Keamatan kependarfluoran CHA secara beransur-ansur menurun dengan peningkatan kepekatan formaldehid. Tambahan pula, jalur kertas yang dimuatkan-CHA telah direka dan digunakan untuk mengesan formaldehid secara kualitatif. Had pengesanan prob CHA kepada formaldehid adalah 0.2 M.
