Novel kinds of dendronized polymers with both functional core and periphery were synthesized by Suzuki polycondensation (SPC) of carbazole-functionalized 2,7-dibromofluorene macromonomers with 9,9-dioctylfluorene-2,7-diboronic ester. The polymers obtained are of high molecular weight and good thermal stabilities. Photoluminescent studies showed that these kinds of dendronized polymers were promising
通过将咔唑官能化的2,7-二溴芴大分子单体与9,9-二辛基芴-2,7-二硼酸酯进行铃木缩聚反应(SPC),合成了既具有功能核又具有外围的新型树枝状聚合物。所获得的聚合物具有高分子量和良好的热稳定性。光致发光研究表明,这类树枝状聚合物是有前途的发蓝光材料,在溶液和薄膜(主要用于第二代)中显示出高量子效率。
