中文摘要：

合成了一系列外围带有咔唑，核心带有或不带有氮杂冠醚结构的1-3代芳醚树枝形聚合物（CZ—Gn—CR，CZ—Gn—OH，n=1-3）．利用光物理方法研究了金属离子Li^＋、Na^＋、K^＋、Ca^2＋．Cu^2＋,Zn^2＋、Eu^3＋和Tb^3＋与树枝形聚合物之间的相互作用．研究表明，Eu^3＋、Tb^3＋和Cu^2＋通过静态过程猝灭树枝形聚合物的荧光，测定了Eu^3＋、Tb^3＋和Cu^2＋对CZ，Gn-CR、CZ-Gn。OH荧光的猝灭速率常数；核心的冠醚结构可以增强树枝形聚合物与金属离子的相互作用．Li^＋、Na^＋、K^＋、Ca^2＋和Zn^2＋对CZ—Gn—CR和CZ—Gn—OH的紫外吸收光谱和荧光光谱均没有明显影响．

英文摘要：

Abstract： A series of poly（aryl ether） dendrimers with carbazole （CZ） at the periphery and with/without a crown ether at the core （CZ-Gn-CR/CZ-Gn-OH, n=1-3） were synthesized. The photophysical properties of CZ-Gn-CR and CZ-Gn-OH were investigated with different concentrations of Li^＋, Na^＋, K^＋, Ca^2＋, Cu^2＋, Zn^2＋, Eu^3＋, and Tb^3＋. There are interactions between the dendrimer and Eu^3＋, Tb^3＋, and Cu^2＋ in the ground state, and the crown ether structure at the core enhances the interactions. The fluorescence of the dendrimers was quenched by Eu^3＋, Tb^3＋, and Cu^2＋ via a static quenching process, and the quenching rate constants were calculated. Li^＋, Na^＋, K^＋, Ca^2＋, and Zn^2＋ have no obvious influence on the UV-absorption and fluorescence spectra of the dendrimers.
