摘　　要：在温和的条件下合成了一种新型的化合物N-正丁基-4-（2-（2-羟乙基氨基）乙氨基）-1,8-萘酰亚胺（ABN）。利用红外光谱、核磁和质谱表征了ABN的结构。在甲醇中,ABN的最大吸收波长为436nm（摩尔消光系数为1.20×10^4 L/mol·cm）,最大荧光波长为522nm（荧光量子效率为0.509）。随着溶剂极性的增加,ABN溶液的吸收和荧光发射光谱发生红移。在二甲基甲酰胺（DMF）/Britton-Robinson缓冲溶液[V（DMF）∶V（Britton-Robinson缓冲溶液）=1∶99]中,ABN的荧光强度随pH值减小而增强,并且在pH=6.73～9.61与pH值呈良好的线性关系。A new compound, N-butyl-4-（2-（2-hydroxyethyl amine）ethyl amino）-1,8-naphthalimide （ABN） was synthesized under the mild conditions. Its structure was characterized by infrared spectrum, nuclear magnetic resonance and mass spectrometry. In methanol, the maximal absorption wavelength of ABN was 436 nm（rnolar extinction coefficient was 1.20 ×10^4 L/mol·cm）,and the maximal fluorescence wavelength was 522 nm（fluorescence quantum efficiency was 0. 509）. Further, the absorption and emission spectra redshifted with the increase of solvent polarity. In V（N, N-dimethyl formamide） ： V（Britton Robinson buffer solution）= 1 ： 99, the fluorescence intensity of the ABN solutions enhanced with the pH decreased,and good linear relationship existed in the pH range of 6.73～9.61.
