摘要

本文描述了两个第三代树状大分子的合成和表征,这些树状大分子由柠檬酸和一个以硫辛酸结尾的树状大分子变体组成。FTIR和C NMR证实了树突状官能团OH、C-O、C=O、C- h和C- s的信号特征。DSC表明,与柠檬酸不同,树状大分子是无定形的。扫描电镜显示了每一代树突状分子中柠檬酸颗粒结构的变化。此外,结构更加均匀。由于酯键,树状大分子是疏水的。接触角bbb90°证实了它们的疏水性。此外,树突末端为硫辛酸的树突可以吸附Cu+2和Fe+3金属离子,可以作为重金属吸附剂。

Synthesis and characterization of a citric and lipoic acids-derived dendrimer
The paper describes the synthesis and characterization of two third generation dendrimers from citric acid and a variant with a dendron terminated with lipoic acid. FTIR and C NMR confirmed the presence of signals characteristic for the dendrimer functional groups OH, C-O, C=O, C-H and C-S. DSC showed that, unlike citric acid, the dendrimer is amorphous. SEM revealed changes in the structure of citric acid particles in each dendrimer generation. In addition, the structure was more homogeneous. Dendrimers are hydrophobic due to ester linkages. Contact angle > 90° confirms their hydrophobic character. Moreover, the dendrimer with a dendron terminated with lipoic acid absorbs Cu+2 and Fe+3metal ions, so it can be used as an adsorbent for heavy metals.
