“…A coumarin based compound produces a peak at 335 nm, while its interaction with Cu 2+ formed a peak at 418 nm, changing the color from yellow to colorless (Li et al, 2019). A benzimidazole-quinoline-based compound (BMQ) results peaks at 342 nm and 418 nm, while the interaction with Cu 2+ forms spectra at 550 nm, changing color from yellow to purple (Liu et al, 2017).…”

The cationic chemosensor based on organic compound bearing an aminophenol moiety as a receptor for metal analyte and a cinnamaldehyde moiety as chromophoric fragment has been developed. In this work, we report the colorimetric sensing of nitrophenyl cinnamaldehyde derivative, namely methyl-3-(2-hidroxy-5-nitrophenyl amino)-3-phenylpropanoate, towards a variety of metal cations, such as Cu2+, Fe3+, Ni2+ and Zn2+. The cation sensing abilities of the sensor were observed for Cu2+and Fe3+ with a color change from colorless to pink and faint yellow, respectively, The characteristic UV-Vis spectra changes were observed upon addition of Cu2+and Fe3+ cations. The hypsochromic absorption spectra shifts were obtained, indicating the cations and sensor complexations had formed. A metal-to-ligand-charge-transfer (MLCT) had occurred and the charge density of the sensor changed resulting in appearance of new absorption peaks in the UV-Vis spectra and color changes of the sensor solution upon addition of the Cu2+and Fe3+.

“…The aromatic heterocycle quinolone, as one of the most widely used organic optoelectronic functional materials, is easy to produce π-π * electronic transition, it exhibits strong fluorescence. 12 Owing to the benzene ring and the imidazole ring being heterocyclic coplanar, benzimidazole presents unique electronic distribution and forms a big π bond system, which is a well-known chromophore used in fluorescence sensing. 13 Compared with the other nitro compounds, TNP not only has a strong electronwithdrawing ability, but also has a strong light absorption capacity at a large excitation wavelength.…”

In this study, a simple fluorescent chemosensor with good fluorescence properties was synthesized, which was used to develop a sensitive and selective sensor for the determination of 2,4,6-trinitrophenol (TNP) and Ag+ in THF/H2O medium based on the fluorescence quenching mechanism. Fluorescence quenching experiments revealed that the fluorescence intensities of the resulted probe were linear with the concentrations of TNP and Ag+ in the concentration range of (30-50)?10-7 and (20-50)?10-7 mol dm-3, with the detection limit of 1.36 and 0.82 ?mol dm-3, respectively. At the same time, accompanied with fluorescent color change under 365 nm UV light irradiation. This has demonstrated that the compound can act as a potential candidate for a ?naked-eye? rapidly detector for Ag+ and TNP in soils and aquatic systems.

A new Light‐Up fluorescent probe (FA‐P) for detection of formaldehyde was designed and synthesized based on the donor‐excited photo induced electron transfer (d‐PeT) process. The probe FA‐P was constructed by integrating a benzothiazole derivatives as the fluorescent skeleton and homoallylamino group as the specific recognition site. It showed the unique advantages of easy‐preparation, and excellent selectivity response toward formaldehyde. Besides, The probe FA‐P can not only detect formaldehyde gas through the prepared test paper, but also detect formaldehyde in serum solution.
