We present the synthesis of ring-opening metathesis polymerization block polymers containing a ruthenium bipyridine luminescent block and a hydrophobic block and end-terminated with a biologically active biotin molecule. These copolymers undergo self-assembly in water into star micelles containing a large number of luminescent Ru(II) centers, with the hydrophobic block in their core and the molecular
我们提出了开环复分解聚合嵌段聚合物的合成,该聚合物包含钌联吡啶发光嵌段和疏水嵌段,并以生物活性生物素分子为末端。这些共聚物在水中自组装成含有大量发光Ru(II)中心的星形胶束,其疏水嵌段位于其核心,分子识别单元生物素位于其外围。蛋白质链霉亲和素的添加导致这些聚合物纳米球通过生物素-steptavidin结合而交联成扩展的网络。除了将其作为将聚合物纳米结构组织成生物化学可寻址网络的方法之外,这项研究还产生了能够与生物化合物结合的发光胶束聚集体,
