This approach offers more straightforward alternative to complex time-consuming analytical techniques. Heavy ions pose significant environmental threat due their potential risks ecosystems human health. review focuses on the latest advancements colorimetric using rhodamine derivatives...

The conventional dyeing technology of textiles using organic dyes is well-known to the majority customers. However, applications colorants are increasingly important for high-tech applications. This has led emergence functional dyes, which used in specialized such as optoelectronics, dye-sensitized solar cells (DSSCs) with high efficiency record ղ% >10, sensing and fluorescence probes anions heavy metal sensitivity can detect ions concentration < 20 nanomole, data storage, light-emitting...

New solid state hydrazone fluorescent reactive disperse dyes based on pyrrolinone ester and temporarily anionic sulfatoethylsulfone moiety were prepared. The NMR of all prepared was studied in details; these observed only pure form as a mixture between E/Z isomers. Spectral properties dye derivatives showed significant fluorescence at low temperature (77 K) well polycrystalline state. dyeing application investigated polyamide 6 wool fabrics. emission spectra the dyed fabrics measured....

The textile-wet process enormously consumes a large volume of water and chemicals, thus awareness cleaner production has been growing to protect the environment from industrial effluents. In this context, reactive dyeing cellulosic materials such as cotton fabrics is major sector textile coloration that necessitates use amount sodium sulfate or chloride alkali exhaust fix dye molecules with macromolecules, respectively. However, remaining salt in effluent badly affect environment. For...

A series of new dyes based on the N ‐analogue Pechmann hybrid were prepared by condensation different 5‐aryl derivatives pyrrolinone ester (phenyl, 4‐bromophenyl, thienyl, and biphenyl) with isatin. ‐Alkylated also using bromoethyl acetate. Full 1 H 13 C NMR assignment was performed. All soluble in most organic solvents: ‐alkylated had better solubility than non‐alkylated derivatives. The UV ‐vis absorption spectra under study are quite similar exhibit maxima 509–526 nm range. No E/Z...

Highly solid-state fluorescent dyes based on phenothiazine bearing sulfa-drug derivatives were successfully prepared and fully characterized by NMR, mass spectra, elemental analysis.
