| 摘 要： | 根据文献合成了第一、第二和第三代羧基为核收敛的多醚树枝状大分子(缩写为G1、G2和G3)。利用振动光谱数据,结合X-衍射结构分析,从G1的结构推想出G2和G3的可能结构。以2,5二甲基苯基醚作为模型分子,把复杂分子拆成组成结构进行光谱分析,从而对产物G1、G2和G3的谱带作了初步归属。

| Abstract: | The 1st, 2nd, and 3rd generations of carboxyl-cored convergent polyether dendrimers (denoted as G1, G2, and G3, respectively) were synthesized following the procedure reported in literature. From the analysis of vibrational spectra of G1, G2, and G3 and the single crystal X-ray structure of G1, the structures of G2 and G3 were supposed. With 2,5 bimethyl benzyl aether as the model molecule of (R=OCH2), the complex molecules were split into their constituent parts, and then their Infrared and Raman spectra were discussed. Based on this, the Infrared and Raman spectra of G1, G2, and G3 were assigned. |
