将不同金刚烷衍生物与3，6-咔唑、2，7-咔唑、N-乙烯基咔唑共聚制备出5个系列蓝光聚合物材料。对共聚物的分子质量、热稳定性、发光性能进行了测试。以10%摩尔分数的金刚烷的共聚物为基准，对不同类型的咔唑-金刚烷共聚物进行对比，以分析咔唑与金刚烷单体结构对共聚物性能的影响。结果表明，侧链型金刚烷-咔唑聚合物聚合度较高，热稳定性较好，但发光性能较主链型共聚物差，波长范围偏蓝紫光区。主链型金刚烷-咔唑共聚物数均分子质量偏低，薄膜态时的最大荧光发射波长均处于蓝光波长范围内。同时，不同金刚烷衍生物引入咔唑主链均能较显著改善其热稳定性，其中二苯基金刚烷引入到咔唑主链形成的共聚物综合性能最好，且低摩尔分数金刚烷的引入可改善共聚物的发光性能。2，7-咔唑与金刚烷聚合获得的主链型共聚物性能比3，6-位咔唑好，是一种非常有应用前景的新型蓝光材料。

Five series of novel blue luminescent materials are successfully prepared through copolymerization between various adamantine derivatives and 3,6-carbazole,2,7-carbazole and N-vinyl carbazole respectively.The molecular weight,thermal stability and luminous properties of the materials are determined.In order to investigate in depth the effects of structure of carbazole and adamantane monomers on the properties of the materials,the different types of carbazole-adamantane copolymers are compared based on the copolymers contained 10% mol of adamantane.It is found that side chain type adamantane-carbazole copolymers have a higher degree of polymerization,better thermal stability,poorer luminescent properties than main chain type adamantane-carbazole copolymers.The emission wavelength of side chain type adamantane-carbazole copolymers locates within the blue-violet light wavelength range.The main chain type adamantane-carbazole copolymers owns lower number average molecular weight and their maximum fluorescence emission wavelengths in the copolymer film state all locate within the blue light wavelength range.The addition of any adamantane derivatives into carbazone main chain can improve significantly the thermal stability of the copolymer,of which,diphenyladamantane exhibits the best.Furthermore,the addition of low content of adamantane can improve the luminescence properties of the copolymer.The main chain copolymer made by 2,7-carbazole has better thermal stability and luminous efficiency than that by 3,6-carbazole.The diphenyladamantane-modified 2,7-carbazole backbone copolymers is expected to have a good application prospect in the preparation of broad absorption spectra and high photoelectric conversion efficiency blue materials.
