“…A colorimetric chemosensor 87 ( Figure 85) based on push-pull dye (8-HQ) for AcO À , CN À and H 2 PO 4 À ions was synthesized, upon the introduction of F À ions. [116] Chemosensor 87 showed an absorption spectrum at the wavelength of 418 nm which was decreased on gradually addition of AcO À , F À , H 2 PO 4 À and CN À ions with the appearance of a new absorption peak at 622 nm. Increments of AcO À and F À ions caused colour change from yellow to purple, whereas changes in colour from yellow-to-green and yellow-to-pink were detected in the case of H 2 PO 4 À and CN À ions, respectively.…”

Among various known hydroxyquinolines, 8-hydroxyquinoline (8-HQ) is the most prevalent moiety due to excellent property for the formation of the complex with different metal ions and anions, and utilized in a wide variety of applications in pharmacological and medicinal fields. 8-Hydroxyquinoline moiety and its analogues acts as fluorophoric ligands on complex formation with alkali and alkaline as well as transition metal ions and anions, thus, considered as an ideal building block in metallo-supramolecular chemistry for recognition, separation, and quantitative investigation of cations. 8-Hydroxyquinoline moiety is also used in various applications for the advancement of novel fluorescent chemosensors in a wide variety of areas viz., material chemistry, bioorganic chemistry, molecular imaging, analytical chemistry, molecular recognition, medical and biological science communities. The present review emphasises on the progress of sensing properties of 8-HQ centred small-molecule fluorescent chemosensors towards several metal ions viz.

“…[9] Demand dyes should have brilliance, a wide spectrum of colours, and outstanding fastness qualities, in addition to their environmental and economic advantages. [10][11][12][13] Textile printing is the process of adding colour to quantities of fabrics to generate artistic designs, Dyes or pigments can be used to colour fibers. The printingpaste should have a high viscosity, which can be produced with a natural or synthetic thickener.…”

Antibacterial Azo Dyes Containing Sulfa Drug Moieties and Their Colour Assessment on Printing Polyester Fabric

2023

Synthesis of a new series of biologically active dyes containing the sulfa drug nucleus and its use in polyester silk screen printing were presented. Synthesis was performed via azo coupling with C and N Nucleophiles. Spectroscopic tools were used to characterize the synthesized azo derivatives. Also, testing of their printing properties, including fastness to washing, light, rubbing, perspiration, and sublimation were evaluated. The new dyes showed respectable fastness and good antibacterial resistance to the growth of certain species of gram‐positive and gram‐negative bacteria. These low‐cost facile synthesized biologically active dyes could be used for sterilizing textiles.

“…Quinoline azobenzene derivatives are interesting for their optical, thermal and electrical properties. Recently, some of physicochemical properties of azo-quinoline derivatives have been studied (Zeyada et al 2013;El-Ghamaz et al 2013Arslan et al 2017;Sankar et al 2007;Sarkar et al 2014;Ghanadzadeh et al 2012;Saylam et al 2014;Yan et al 2013;Szala et al 2017), but knowledge of these compounds and their light-induced behavior remains low. Finding systems showing attractive optical response is very important for their practical use in photonics and optoelectronics.…”

We present the optical and photochromic properties as well as surface quality of thin films of the methacrylic copolymers containing 2-methylquinoline and quinoline azo-dyes in side chain. The extinction coefficient and refractive index were determined using spectroscopic ellipsometry combined with transmittance measurements. Photo-responsive behavior was investigated by determination of trans–cis photoisomerization rates under irradiation with unpolarized 365 nm light. We found that optical properties as well as photoisomerization rates of investigated polymers are dependent on the presence of a methyl substituent in the 2nd position of the quinoline moiety. The quality of the thin films was examined using Atomic Force Microscopy measurements.
