Tetra-substituted palladium phthalocyanine complexes with different electron withdrawing and electron donating substituents (–H, –NO2, –NH2, –Cl, –COOH, aryl thio) have been synthesized with a good yield. The synthesized complexes were characterized using XPS, UV–Vis, IR, Raman, XRD, TGA and electrochemistry. The XPS spectra show that the central metal ion is in the +2 state, while the UV–Vis spectra
具有不同吸电子和给电子取代基(–H,–NO 2,–NH 2的四取代钯酞菁配合物(-Cl,-COOH,芳硫基)的合成产率很高。使用XPS,UV-Vis,IR,拉曼,XRD,TGA和电化学对合成的复合物进行表征。XPS光谱表明,中心金属离子处于+2态,而UV-Vis光谱则表明,由于存在除单体以外的二聚和低聚分子,因此在Q-波段600-700 nm处出现了吸收峰。物种。UV-Vis和拉曼光谱显示出峰/峰的移动,这是与母体钯酞菁相比,苯环外围的吸电子和给电子取代基的结果。热重稳定性研究表明,这些配合物经历了两个独立的分解过程。不同配合物的热稳定性按以下顺序排列:PdPc
