摘要
以N-羟甲基苯甲酰胺与β-萘酚为原料制备了荧光化合物α-N-甲基苯甲酰胺-β-萘酚。采用FT-IR、1 HNMR、元素分析仪表征了产物结构。利用Gauss03程序包6-31G机组优化化合物结构,得到化合物最优结构的键长、键角。利用紫外可见分光光度计、荧光分光光度计检测化合物的光学性质。通过探讨反应物物质的量比、催化剂与反应溶剂的体积比、反应温度和反应时间对反应产率的影响,得到最佳反应条件为:n(β-萘酚)∶n(N-羟甲基苯甲酰胺)=1∶1.25,V(催化剂)∶V(溶剂)=1∶10,反应温度控制在40℃回流反应7h,此条件下产率为88%。化合物的最大吸收波长为280nm,发射峰分别为348nm和359nm,359nm处的发射峰略低。
α-N methy benzoyl amide-β-naphthol was synthesized from substituted β-naphthol and N-（hydroxy- methyl）benzamide. FT-IR, 1HNMR and element analyzer were used to characterize the structure. The structure was optimized through the programme Gauss03 package implementing the 6-31G basis set. The influence of the molar ratio of reactant, the volume ratio of catalyst and solvent, reaction temperature and reaction time had also been studied in detail. Optical property was investigated using UV- vis spectrophotometer and fluorescent spectrometer. The optimum reaction conditions were： n（l？-naphthol） ： n （N-（hydroxymethyl） benzamide）= 1 = 1.25, V （catalyst） ： V （solvent） = 1 ： 10,reaction temperature was 40℃, reaction time was 7h and the yield was 88%. UVvis spectra showed λmax = 280nm Fluorescence spectra showed two emission peaks which were 348nm, 359nm and the peak of 359nm was lower.
