以价廉易得的原料，采用简便的方法，成功地合成了两个系列的蒽醌染料衍生物[CNU-1 ~ CNU-7和CNU-8 ~ CNU-10]。所合成的蒽醌染料均经1H NMR、13 C NMR、UV-Vis光谱和HRMS表征。染料的紫外-可见吸收光谱表明，染料的吸收波长在590-655 nm之间，为蓝色染料。以超临界二氧化碳为绿色介质，用这些化合物对涤纶织物进行染色。所有的化合物显示深色调和优异的染料固定，即使在低浓度（0.5%）。在牢度试验中，CNU-1 ~ CNU-10的耐洗牢度（4-5）、耐汗牢度（4-5）和耐光牢度[CNU-1 ~ 7（4-5），CNU-8 ~ 10（2-3）]均表现出优异的结果。因此，我们的结果表明，这些类型的蒽醌染料是商业上最可接受的，它们实际上表现出令人满意的颜色均匀性。
Two series of anthraquinone dye derivatives [CNU-1toCNU-7andCNU-8toCNU-10] have been successfully synthesized from commercially inexpensive and readily available starting materials by using simple and convenient methods. All synthesized anthraquinone dyes were characterized by1H NMR,13C NMR, and UV–Vis spectroscopy and HRMS. The UV–Vis spectra of the dyes indicated that the absorption wavelengths of dyes were approximately 590–655 nm, which indicated that these are blue dyes. Polyester fabrics were dyed with these compounds using supercritical carbon dioxide as a green medium. All the compounds displayed deep color shades and excellent dye fixation even at low concentrations (0.5%). In the fastness experiments, compoundsCNU-1toCNU-10all exhibited excellent results in washing (4–5), sweat (4–5) and lightfastness [CNU-1to7(4–5),CNU-8to10(2–3)]. Hence, our results revealed that these types of anthraquinone dyes are commercially most acceptable, and they practically exhibited satisfactory color uniformity.
