中文摘要：
基于杯芳烃对分子的识别特性和量子点的高荧光特性，合成了脱叔丁基杯[6]芳烃的溶胶凝胶修饰二氧化硅包覆的碲化镉半导体纳米粒子，得到了新型的水溶性复合纳米粒子，并用。HNMR谱图、红外光谱、荧光光谱、紫外光谱、透射电镜进行了表征，并以新型的水溶性复合纳米粒子为荧光探针对客体分子乙二胺进行了识别和检测，使得乙二胺在5．0～150．0nmol·L^-1范围内具有良好的线性关系，r=0．99913，最低检出限为5．7Onmol·L^-1。此荧光探针与客体分子乙二胺之间的相互作用，借以朗缪尔等温式加以解释，验证了新型的荧光探针对分子的识别具有高灵敏度、高荧光性、高选择性和高稳定性等优越特点。
