摘　　要：由 1-氨基蒽醌与不同偶合基合成了 8个含蒽醌基单偶氮染料 ,对其进行了元素分析、红外光谱和紫外光谱表征。对其紫外吸收光谱的研究表明 ,当偶合基由 2 -羟基 - 3-氨替酰氨萘酚变为 2 -羟基 - 11氢-苯并咔唑 - 3-氨替酰氨萘酚时 ,偶氮染料的吸收红移 130 nm。用紫外灯光和红外灯光对 8个偶氮染料进行了光照实验 ,发现紫外光照会引起偶氮染料 DMF稀溶液减色 ,没有观察到 N N双键的顺反异构吸收变化。In this report, the design and synthesis of photogenerating azo pigments from 1\|aminoanthraquinone were described. New azo pigments were synthesized by coupling 1\|aminoanthraquinone with various coupling. Compounds, elementary IR spectrum analysis indicated that the systhesis and purification was successful. When the coupler was changed from 2\|hydroxy\|3\|naphthanilide to 2\|hydroxy\|11H\|benzolcarbazole\|3\|carboxanilide, a red shift of 130 nm was obtained. When the pigments in DMF were irradiated with the light from a high pressure mercury lamp, the absorption of the pigments decreased.
