摘要

利用密度泛函理论（DFT）模拟分析了吲哚啉化学反应的可行性。以吲哚啉为偶联组分合成了一系列偶氮分散染料，即 D1-D6。对合成的染料进行了紫外-可见光、傅立叶变换红外光谱、1H-核磁共振和质谱分析。应用 DFT 模拟分析了所设计染料的光谱特性。对聚对苯二甲酸乙二酯（PET）和尼龙（PA）织物的染色进行了评估和比较。合成的吲哚啉偶氮分散染料在 PET 和 PA 织物上呈现出黄色至红色的色调。在 PET 和 PA 织物上，随着染料浓度 D1 和 D2 的增加，可获得深色调。摩擦牢度和升华牢度极佳。利用 DFT 计算研究了染料结构与 PET 和 PA 织物染色性能之间的相互关系。

Investigation of novel indoline azo disperse dyes: synthesis, DFT simulation, and dyeing performance on PET and PA fabrics†

The feasibilities of the chemical reactions of indoline were analyzed with density functional theory (DFT) simulation. A series of azo disperse dyes using indoline as a coupling component were synthesized, namely D1–D6. The synthesized dyes were investigated by UV-visible, FT-IR, ¹H-NMR and MS spectroscopies. DFT simulation was applied to analyze the spectrometric properties of designed dyes. The dyeing of polyethylene terephthalate (PET) and nylon (PA) fabrics were assessed and compared. The synthesized indoline azo disperse dyes exhibited a yellow to red hue on the PET and PA fabrics. Deep shades were achieved with increased dye concentrations for D1 and D2 for the PET and PA fabrics. Excellent rubbing fastness and good sublimation fastness were achieved. Interrelations between dye structures and dyeing performance on the PET and PA fabrics were investigated using DFT calculations.
