摘　　要：合成了 5种对羧基苯基重氮基 β -二酮化合物 ,并与光致变色化合物相连 ,得到 5种新型的多功能化合物 .用元素分析、IR ,1HNMR和MS确定了其结构 ;研究了其紫外 -可见光谱、荧光光谱及光致变色性 ;对化合物与Eu生成的配合物与DNA相互作用的性能进行了初步探讨 。Five p-carboxylphenylazo-β-diketone compounds were synthesized. Then they were linked with photochromic compound to give five new multiple-functional compounds. Their structures were determined by 1 H NMR , IR, MS and elemental analysis. Their UV-absorption spectrum, fluorescence spectra and photochromic properties were studied. The mechanism of the interaction between their Eu(Ⅲ) complex and CT DNA was studied, and the results for different complexes were compared.
