| 摘 要： | 有机超微粒是国际上刚刚起步的研究领域，是纳米科技领域和有机光电子领域的重要前沿课题．本文通过卤化、酯化、Wittig—Horner和Sonogashira偶联等一系列反应合成了以二苯并环庚三烯为端基的有机功能小分子（DPMB-SH）．通过DPMB-SH中巯基和纳米金的相互作用，观察到了以纳米金为载体的聚集诱导荧光增强（Aggregation—Induced Emission，AIE）现象，为考察有机小分子在较小纳米尺寸（〈10nm）的AIE效应提供了一种简便的方法．

| Abstract: | The search for ways to control the size,shape and hence properties of organic molecular crystals,which is well established for inorganic crystals,was an important aspect of possible developments in nanoscience. In this article,by halogenation,esterification,Wittig-Horner and Sonogashira reaction,a functional low molecular weight organic molecule of dibenzosuberenylidene derivative (DPMB-HS) was synthesized and characterized by 1H NMR,13C NMR,and MS (ESI). An aggregation induced emission (AIE) was found when... |
