【摘要】 以氯亚铂酸钾和自合成的5,10,15,20-四(4-羧基苯基)卟啉为原料合成了铂(Ⅱ)配合物。采用元素分析、电导测定、紫外-可见光谱、红外光谱、核磁共振和电喷雾质谱等多种物理手段表征了钯配合物的结构,对配合物的空间构型和成键性质进行了讨论。研究了配合物在氮气气氛中的热分解行为。结果表明:该配合物属于低自旋的平面正方形,配合物中离域π键和螯合环的形成使Pt-N键加强,配合物很稳定。更多还原

【Abstract】 In this paper,ligand of meso-tetra(4-carboxyphenyl)porphyrin has been synthesized,and platinum(II) complex was obtained by the reaction of the ligand and platinous potassium chloride.Molecular structures of the synthesized compound was confirmed by elemental analysis,conductivity measurement,UV-Vis spectra,IR spectra,1H NMR spectra and ESI-MS.The configuration and bonding character of complex were discussed.Thermogravimetry(TG) and differential scanning calorimetry(DSC) for complex in an atmosphere of N2 were performed.In the chelating ring,conjugate π bonds were formed,which further strengthen the Pt-N coordination bonds and made Pt(II) complex a stable compound.更多还原
