两个对二偶氮苯的合成

Synthesis of Two p-diazobenzene Compounds

摘要

摘要: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

Abstract: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
