摘　　要：合成了5,10,15,20-四(4-羧基苯基)卟啉配体,并与氯化钯反应得到钯配合物。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配体及其钯配合物的结构,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。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Pd—N键加强,配合物很稳定。in this paper, the ligand of meso-tetra （4-carboxyphenyl ）porphyrin was synthesized, and a palladium （ Ⅱ ） complex was obtained by the reaction of the ligand with palladium chloride. Molecular structures of the synthesized compounds were confirmed by elemental analysis, conductivity measurement, UVVis spectra, IR spectra, ^1HNMR spectra and ESI-MS. The configuration and bonding character of the complex were discussed. Thermogravimetry （TG） and differential scanning calorimetry （DSC） for two compounds in an atmosphere of N2 were performed. In the chelating ring, the conjugated π bonds were formed, which could further strengthen the Pd-N coordination bonds and make the Pd （ Ⅱ ） complex a stable compound.
