Synthesis, spectral study and application of solid state fluorescent reactive disperse dyes and their antibacterial activity

Popis výsledku v původním jazyce

New solid state hydrazone fluorescent reactive disperse dyes based on pyrrolinone ester and temporarily anionic sulfatoethylsulfone moiety were prepared. The NMR of all prepared dyes was studied in details; these dyes were observed only in pure hydrazone form as a mixture between E/Z isomers. Spectral properties of prepared dyes were studied and all dye derivatives showed significant fluorescence at low temperature (77 K) as well as in polycrystalline solid state. The dyeing application of these dyes was investigated on polyamide 6 and wool fabrics. The emission spectra on the dyed fabrics were measured. The antibacterial activity of the reactive disperse dyes as well as dyed fabrics at different concentrations was studied against Staphylococcus aureus as Gram-positive bacteria and Escherichia coli as Gram-negative bacteria. The dyed samples exhibited a higher antibacterial activity compared with selected antibiotics as reference standard.
