【摘要】 以二氯化钯和2,2,6,6-四甲基-3,5-庚二酮为原料,在甲醇中合成了一种新的β二酮前驱体—双(2,2,6,6-四甲基-3,5-庚二酮酸)钯(Ⅱ)。通过元素分析、红外光谱、核磁共振氢谱和单晶X射线衍射技术对其进行了表征,确定了配合物的结构组成。用热重法分析了配合物在氮气气氛中的热分解行为,当温度升到295℃,前驱体基本挥发完全,表明双(2,2,6,6-四甲基-3,5-庚二酮酸)钯(Ⅱ)是一种理想的MOCVD前驱体。更多还原

【Abstract】 A new precursor,bis(2,2,6,6-tetramethyl-3,5-heptanedionato)palladium was synthesized from PdCl2 and Hthd in methanol.The structure of bis(2,2,6,6-tetramethyl-3,5-heptanedionato) palladium was characterized by element alalysis,infrared spectroscopy,1HNMR spectroscopy and X-ray diffraction analysis.Thermal decomposition properties was studied by thermogravimetric analysis under nitrogen atmosphere.The results showed that bis(2,2,6,6-tetramethyl-3,5-heptanedionato) palladium was an ideal precursor for it was completely volatiled at 295℃.更多还原
