A novel mixed‐ligand complex of [In(Me‐phen)Cl3(DMSO)](1) was acquired and specified via spectral approaches (IR, UV–Vis, 1H‐NMR, and luminescence), thermal evaluation such as thermogravimetric, differential thermal analyses, and single‐crystal X‐ray diffraction. In this study, we have also reported the nanosize of [In(Me‐phen)Cl3(DMSO)](1) that has been synthesized via the sonochemical process. Characterization of nanoparticle(1) was carried out via X‐ray powder diffraction, scanning electron microscopy, and Fourier transform infrared spectroscopy. The sample size assembled via the sonochemical approach was approximately 20 nm. Also, a novel screen‐printed electrode modified with indium nanocomplex (In NC/SPE) was developed. An electrochemical examination of the adjusted electrode in addition to its efficiency in dopamine electro‐oxidation is explained. It was proven that dopamine oxidation at adjusted electrode surface takes place at 150 mV potential less positive compared to an unadjusted screen‐printed electrode. The relevant detection limit for dopamine was 2.0 × 10−7 M via differential pulse voltammetry. Moreover, the adjusted electrode was utilized to simultaneously determine dopamine and acetylcholine. Lastly, the adjusted electrode was utilized to determine dopamine and acetylcholine within real specimens.

电化学修饰多巴胺和乙酰胆碱的铟（III）配合物的声化学合成和晶体结构
通过光谱方法（IR，UV-Vis，1 H-NMR和发光），热分析等方法获得并指定了一种新型的[In（Me-phen）Cl 3（DMSO）] （1）的混合配体配合物。热重分析，差示热分析和单晶X射线衍射。在这项研究中，我们还报告了通过声化学过程合成的[In（Me-phen）Cl 3（DMSO）] （1）的纳米尺寸。纳米粒子的表征（1）通过X射线粉末衍射，扫描电子显微镜和傅里叶变换红外光谱进行。通过声化学方法组装的样品大小约为20 nm。此外，还开发了一种用铟纳米复合物（在NC / SPE中）修饰的新型丝网印刷电极。除了对多巴胺电氧化的效率外，还介绍了对调节电极的电化学检查。事实证明，与未经调整的丝网印刷电极相比，经过调整的电极表面多巴胺氧化发生在150 mV的正电位下。多巴胺的相关检出限为2.0×10 -7M通过差分脉冲伏安法。此外，调节电极用于同时测定多巴胺和乙酰胆碱。最后，将调节后的电极用于确定真实样品中的多巴胺和乙酰胆碱。
