用邻氨基苯甲(o-ABA),间氨基苯甲酸(m-ABA),对氨基苯甲酸(p-ABA)和甲基丙烯酰氯为原料合成了邻甲基丙烯酰胺基苯甲(o-MAABA),间甲基丙烯酰胺基苯甲酸(m-MAABA)和对甲基丙烯酰胺基苯甲(p-MAABA),通过^1H NMR,元素分析确认了其结构。详细考察了所得化合物的荧光性能,发现o-MAABA和p-MAABA在358nm处有最大激发波长,而m-MAABA则在324nm处,它们在最大激发波长下的发射波长都位于420nm左右的蓝光区域,o-MAABA强度最强,p-MAABA最弱。
o, m, p-(Methacrylamido)benzoic acid (o, m, p-MAABA)was synthesized from o, m, p-aminobenzoic acid (o, m, p-ABA), elemental analysis and ^1H NMR were used to confirm these compounds. The fluorescent properties of the compounds were investigated. The result showed that o, p-MAABA has λmax^ex at 358 nm while m-MAABA has λmax^ex at 324 nm. Excited at λmax^ex, o-MAABA had the strongest fluorescence, while p-MAABA had the weakest, and all of them were round at 420 nm.
