摘要

首先合成氢杨梅素-铜(DMY-Cu（Ⅱ）)配合物，通过紫外光谱、红外光谱、热重－热差分析(TG-DTA) 及元素分析对DMY-Cu（Ⅱ）金属配合物的结构进行表征.结果表明，DMY易与Cu

形成配合物，其组成为[C

O.进一步地研究了DMY-Cu（Ⅱ）金属配合物对超氧阴离子自由基(O

·)、羟基自由基(OH·)及DPPH 自由基（DPPH·）的清除作用，结果发现DMY-Cu（Ⅱ）配合物对OH·、O

· 和DPPH·具有显著的清除效果，且清除效果比单独配体DMY更强.

Abstract

This paper characterizes the structure of metal complex DMY-Cu（Ⅱ）after its preparation through UV spectroscopy

IR spectroscopy

elemental analysis and thermogravimetry-differential thermal analysis (TG-DTA). The results indicate that DMY and Cu

ion are easy to form complexes whose composition is [C

]

·H

O. It further studies the scavenging capacity of DMY-Cu（Ⅱ）on superoxide anion radical (O

·)，hydroxyl radical (OH·)and DPPH radical（DPPH·）. The finding of the investigation is that the complex DMY-Cu(Ⅱ) has a great cleaning effect on OH·

· and DPPH·

which outweighs the DMY ligand.
