Abstract

A novel Schiff base derivative L (N1-(thiophene-2-ylmethylene)benzene-1,2-diamine) was synthesized via condensation reaction of 3-thiophene carboxaldehyde and 1,2-diamino benzene. The synthesized compound was authenticated using 1 H NMR, 13 C NMR, HRMS, and IR spectroscopy. The compound L was found to be a Fe3+ sensor with the complexation ratio of 1 : 3 as revealed by Job’s plot with maximum absorption at 318 nm. The photophysical properties were studied using absorption and emission spectra. DFT and TD-DFT studies were carried out in order to support the photophysical outcomes of compound L. An antioxidant behaviour of compound L was studied using TAC, FRAP, and DPPH assays and it was found to be showing better TAC activity than the used standard i.e. gallic acid.

新型希夫碱作为Fe3+传感器和抗氧化剂及其理论研究

通过3-噻吩甲醛与1,2-二氨基苯的缩合反应，合成了新型希夫碱衍生物L (N1-(噻吩-2-基亚甲基)苯-1,2-二胺)。合成的化合物经1h NMR、13c NMR、HRMS和IR光谱鉴定。化合物L是Fe3+传感器，其络合比为1:3，在318 nm处最大吸收。利用吸收光谱和发射光谱研究了其光物理性质。为了支持化合物L的光物理结果，进行了DFT和TD-DFT研究。使用TAC、FRAP和DPPH分析研究了化合物L的抗氧化行为，发现它比使用的标准物(即没食子酸)显示出更好的TAC活性。

期刊介绍： Main Group Chemistry is intended to be a primary resource for all chemistry, engineering, biological, and materials researchers in both academia and in industry with an interest in the elements from the groups 1, 2, 12–18, lanthanides and actinides. The journal is committed to maintaining a high standard for its publications. This will be ensured by a rigorous peer-review process with most articles being reviewed by at least one editorial board member. Additionally, all manuscripts will be proofread and corrected by a dedicated copy editor located at the University of Kentucky.
