摘要： 以1-（4-溴苯基）金刚烷为原料，经醛化反应和Wittig反应合成了单体对金刚烷基苯乙烯. 然后通过对金刚烷基苯乙烯和乙烯基咔唑的共聚，合成了不同金刚烷摩尔含量的共聚物（乙烯基咔唑-对金刚烷基苯乙烯）. 采用FTIR、1HNMR和元素分析等对各产物及共聚物结构进行了表征，通过凝胶色谱仪和荧光光谱仪考察了金刚烷含量对共聚物分子量和光学性能的影响. 结论表明，金刚烷基团的引入，共聚物的发光色纯度和发光效率均有提高.

Abstract: The 4-(1-adamantyl) styrene was synthesized by the hydroformylation reaction and Wittig reaction with 1-(4-bromophenyl) adamantane as raw material. And then the copolymer p(NVK-co-AdSt) with different content of adamantane were prepared by copolymerization of 4-(1-adamantyl) styrene and vinyl carbazole. The structures of the products and copolymers were characterized by FTIR, 1HNMR and elemental analysis. The effects of adamantane content on the molecular weight and optical properties of the copolymers were investigated by gel chromatography and fluorescence spectroscopy. The results showed that the introduction of adamantane groups, the color purity and luminous efficiency of the copolymers were improved.

Key words: Vinyl carbazole, 4-(1-adamantyl) styrene, photoluminescence properties, steric hindrance
