| 摘 要： | 本文报道以聚苯并咪唑(PBI)与某些过渡金属卤化物所形成的金属复合物的XPS研究,由反映在金属复合物N_(1s)和C_(1s)振起(Shake-up)伴峰的消失,反映在PBI中N_(1s)双峰变为复合物中的具有高结合能的单峰以及与其复合金属离子结合能的降低,这就从施受两个侧面确证金属复合物的形成。XPS结果也说明在金属复合物的制备中,不同溶剂条件所制得的复合物在硅氢加成中活性丧失归结於溶剂导致的金属离子的还原。

| Abstract: | Three novel polybenzimidazole metal complexes, FBI H2PtCl6( I ), FBI RhC13( Ⅱ) and FBI PdCl2 (Ⅲ) were synthesized and characterized by X-ray Photoelectron Spectroscopy (XPS). The formation of the polymer metal complexes was confirmed by the disappearance of the shake-up satellites of N1sadn C1s in ( I )-(Ⅲ)and by the coalescence of the two peaks of N1s in complexes resulting in an increase of lower binding energy of N1s peak and decrease of binding energy of the metallic ion respectively. The experimental results of XPS showed that different solvent used for preparation of polymer metal complexes greatly affected the catalytic activity. |
