摘要

以3，4，9，10-苝四甲酸二酐（PTTC）为原料，采用真空气相沉积-分子自组装法制备了有机纳米材料，通过扫描电镜、透射电镜、红外光谱、荧光光谱和差热分析表征所得产物。用吐温20增溶PTTC纳米材料，发现L-赖氨酸对该分散系的荧光具有较强的增敏作用，据此建立了L-赖氨酸的纳米荧光化学传感新方法。体系的荧光变化与赖氨酸浓度呈线性关系，线性范围为7.0010

Abstract

Organic nanomaterial PTTC was prepared by directly self-assembling in the gas phase with a thermal vacuum evaporation process. The product was characterized by scanning electron microscopy (SEM)

transmission electron microscopy (TEM)

infrared spectrum(IR)、fluorescence spectrum and differential thermal analysis(DTA). The PTTC nanomaterial can be solubilized in the solution of Tween 20

and L-lysine has strong sensitizing effect for the fluorescence of the dispersion system. A nano-fluorescent chemical sensor of L-lysine is built based on the above results. The linear range is 7.0010

and it is expected to prepare a nano electrochemical sensor of L-lysine in the future.
