摘要

从9-氯吖啶1开始，通过胺化、重氮化和与罗丹宁类似物6 (A, b)或其他偶联伙伴9 (A, b)、11和13偶氮化，以很好的收率制备了一系列含有吖啶发色团的偶氮染料，标记为8 (A -d)、10 (A, b)、12和14。利用红外光谱(FT-IR)、核磁共振氢谱(1H NMR)和质谱分析确定了偶氮分散染料的结构。此外，合成的偶氮染料被用来制备浆料，用于用经典的丝网印刷技术印刷聚酯织物。对染料的色强和牢度性能进行了测试，结果表明，染料具有良好的耐洗涤、耐摩擦、耐汗水、耐升华和耐光照的牢度。进一步筛选染料对革兰氏(+)和革兰氏(-)细菌的体外抗菌活性。其中大多数对这些被试生物显示出有希望的活性。

Synthesis, characterization, and antibacterial activity of azodyes incorporated acridine chromophore and their applications in polyester printing

A series of azo dyes incorporated acridine chromophore labelled as 8 (a-d), 10 (a, b), 12 and 14 were prepared in very good yields starting from 9-chloroacridine 1 followed by amination, diazotization and coupling either with rhodanine analogues 6 (a, b) or other coupling partners 9 (a, b), 11 and 13. FT-IR, 1H NMR, and mass spectroscopic analysis were used to establish the structures of the produced azo dispersed dyes. Moreover, the synthesized azo dyes were used to prepare pastes that were used to print polyester fabric using classic silk-screen printing techniques. The dyes were tested for color strength and fastness properties, and they showed good fastness resistance to washing, rubbing, and perspiration, as well as fastness to sublimation and light. The dyes were further screened for their in vitro antibacterial activity against both Gram (+) and Gram (-) bacterial species. Most of them showed promising activities against these tested organisms.
