Singh, Rajeev Kumar published the artcileApproaches to synthesis of asycyanine colourants and their characterisation, Related Products of iodides-buliding-blocks, the publication is International Journal of Chemical Sciences (2007), 5(3), 1229-1235, database is CAplus.

The number of asycyanine colorants (ACC) are synthesized by the catalytic condensation of auxochromic chalcones such as 4-dimethylaminostyryl 4-nitrophenyl ketone and 4-dimethylaminostyryl 4-methoxyphenyl ketone with different electron rich quaternized azo-heteroaromatics These ACC were obtained with a view to assess their electronic absorptivity. The ACC were found to absorb at longer wavelengths and to show uniform bathochromic shifts compared with the unsubstituted colorants and β-substituted styrylogues. The wavelengths of ACC were in good agreement that weighing at 6-substitution in the heterocyclic systems affect as follows: I > Br > Cl > H and OEt > OMe > Me > H.

M. published the artcileSynthesis, Dynamics of Solvatochromism and pH-sensory of Novel Push-π-pull Phenothiazine-quinoline Fluorophore Toward Turn-on Fluorescent and Colorimetric Test Strips, Safety of 1-Ethyl-2-methylquinolin-1-ium iodide, the publication is Fibers and Polymers (2022), 23(5), 1182-1189, database is CAplus.

Novel donor-central-π-bridge-acceptor (E)-1-ethyl-2-((10-hexyl-10H-phenothiazin-3-yl)methylene)-2,4a-dihydroquinolin-1-ium (PTZ-Q) fluorophore with remarkable solvatochromism, high fluorescence and pH-sensory properties was designed and synthesized in good yield. PTZ-Q sensor was fully characterized utilizing various spectroscopic techniques, including IR (FTIR), ¹H/¹³C NMR, and mass spectroscopic methods. UV-Vis absorption spectra of the prepared donor-acceptor PTZ-Q were explored in different solvents of varying polarities to show pos. solvatochromism related to intramol. charge transfer. Addnl., the fluorescence spectra of PTZ-Q displayed strongly solvent-dependent wavelength and band intensity. Stokes′ shifts were found to increase upon increasing the polarities of solvents up to 3984 cm^-1 for the highest polar solvents. Linear energy-solvation correlation was employed to examine solvent-dependent Stokes′ shift. Quantum yields () of PTZ-Q were determined The pH-dependent absorption and emission spectra in DMF were also explored. The UV-Vis absorption intensity was monitored at 522 nm, while the emission intensity was detected at 603 nm in DMF. The pH sensing mechanism was found to depend on proton abstraction to the PTZ-Q fluorophore to result in colorimetric and fluorescent spectral changes associated with a colorimetric shift from yellow to pink, red and purple. The synthesized PTZ-Q probe was utilized to fabricate colorimetric and fluorescent test strips with the ability to detect pH changes in aqueous media, which was verified with CIE Lab color coordinates.

Han, Qian published the artcileA redox-switchable colorimetric probe for “Naked-Eye” detection of hypochlorous acid and glutathione, Synthetic Route of 606-55-3, the publication is Molecules (2019), 24(13), 2455, database is CAplus and MEDLINE.

We report the development of a new colorimetric probe (L-ol) for investigations of the redox process regulated by hypochlorous acid (HOCl) and glutathione (GSH). The HOCl/GSH redox-switching cycle process was investigated in detail by UV-visible absorption spectroscopy, colorimetric anal. assay and high-resolution mass spectrometry (HRMS). The switchable absorbance responses were attributed to the HOCl-induced oxidation of the p-methoxyphenol unit to the benzoquinone derivative (L-one) and sequential reduction of L-one to hydroquinone (L-ol’) by GSH. In phosphate-buffered saline (PBS) buffer, the absorbance of L-ol at 619 nm underwent a remarkable bathochromic-shift, accompanied by a color change from pale yellow to blue in the presence of HOCl. With further addition of GSH, the absorbance of L-one exclusively recovered to the original level. Meanwhile, the blue-colored solution returned to the naive pale yellow color in the presence of GSH. The detection limits for HOCl and GSH were calculated to be 6.3 and 96 nM according to the IUPAC criteria. Furthermore, L-ol-loaded chromatog. plates have been prepared and successfully applied to visualize and quant. analyze HOCl in several natural waters.
