: In this work, the important features, electrochemical, optical and thermal stability as antioxidant, of four new donor-acceptor–π–acceptor-donor architecture, antioxidant dyes based on thiadiazole were studied. The four dyes carry aryl amino groups as the donors, two 1, 3, 4-thiadiazole moieties as the acceptors and azo and phenyl groups as π spacers. The effect of different aryl amino substituents as the donor group on optimization molecules, geometric, optical properties and electronic properties were studied and discussed. These azo dyes were synthesized by diazotization of 1, 4-bis (2-amino-1,3,4 -thiadiazole)benzene and coupling with different aromatic compounds, and their structures were recognized by UV spectroscopy and 1H NMR, FTIR, and elemental analysis. Interestingly, these compounds proved to be as important for lubricants as antioxidants. Outcome of run Density functional theory DFT-based quantum calculations on these dyes so allow comprehensive information in correlation with their cell high performance. Electron donor substrate based on organic solar cells shows power conversion efficiency (PCE) of 5.3 % with 0.93 as high open-circuit voltage by simple solution spin-coating manufacturing procedure. The efficiency of the prepared azo day passes to inhibition base oil from oxidation.
:在这项工作中,研究了四种基于噻二唑的新型供体-受体-π-受体-供体结构抗氧化染料的重要特征、电化学、光学和热稳定性。这四种染料以芳基氨基为给体,两个 1,3,4-噻二唑分子为受体,偶氮和苯基为 π 间隔物。研究和讨论了不同芳基氨基取代基作为给体基团对优化分子、几何特性、光学特性和电子特性的影响。这些偶氮染料是通过重氮化 1,4-双(2-氨基-1,3,4-噻二唑)苯并与不同的芳香族化合物偶联合成的,并通过紫外光谱、1H NMR、FTIR 和元素分析确认了它们的结构。有趣的是,这些化合物被证明对润滑剂和抗氧化剂同样重要。对这些染料进行基于密度泛函理论(DFT)的量子计算,可获得与其电池高性能相关的全面信息。通过简单的溶液旋涂制造工艺,基于电子供体基底的有机太阳能电池的功率转换效率(PCE)达到 5.3%,开路电压高达 0.93。所制备的偶氮日的效率与抑制基础油氧化有关。
