water-soluble hyperbranched polymer containing boronic acid groups at the ends of the polymer, which are capable of binding to diol-containing mannose, was syntheized. The hyperbranched polymer was prepared by a palladium-catalyzed Suzuki cross-coupling reaction using the tribromo monomer for the hyperbranched type structure. The water-soluble hyperbranched polymer (HP) exhibited enhanced fluorescence
合成了在聚合物末端含有硼酸基团的水溶性超支化聚合物,其能够与含二醇的甘露糖结合。超支化聚合物是通过钯催化的Suzuki交叉偶联反应制备的,其中三溴单体用于超支化型结构。与其他蛋白(如溶菌酶和细胞色素c)相比,水溶性高支化聚合物(HP)在存在甘露糖的情况下暴露于凝集素时显示出增强的荧光强度,因为甘露糖在结合凝集素和HP中起关键作用,从而导致选择性传感朝向凝集素。
