摘要: Abstract A series five coumarin azo disperse dyes with thiophene bridge are synthesized using diazotized aniline derivatives which confirmed by FT-IR, 1H NMR, 13C and CHN analysis. The applied on polyester nylon material. multifunctional properties (lightfastness, washing fastness, sublimation K/S, UPF, antimicrobial activity) of the dyed fabric determined. dye 3a (-NO2) show red shifted absorption (649 nm) blocking 95.5–97.4% UV radiations 96% property. geometries all optimized Density Functional Theory (DFT). Global Reactivity Descriptors (GRD) evaluated at same method theory. GRD obtained shows a linear relation lightfastness UPF ratings. activity determined AATCC 100 test it is correlated HOMO-LUMO energy band gap.
