设计并合成了对-二[(2,4-二羟基苯基)偶氮基]苯和对-二[(5-甲基-2-羟基苯基)偶氮基]苯两个二偶氮化合物,用红外和元素分析证实了相应结构与所设计结构相符。两个化合物均在300~500 nm 之间有较强的吸收,是良好的紫外吸收材料。%p-bis [(2,4-dihydroxyphenyl)azo-y1]benzene and p-bis [(5-methy1-2-hydroxyhheny1)azo-y1]were designed and synthesized.Infrared spectrum spectra and elemental analysis were used to confirm the structure of the two compounds. Both compounds showed strong absorption in range of 300~500 nm,indicating that they are good UV-absorbing materials.
