functionality using 1,4‐benzenediboronic acid as the coupling partner in the presence of palladium catalyst gave the desired polymer. A different sequence of the same procedure was also employed to yield polymer with essentially identical structure. In the reverse sequence mode, low molar mass monomer (2,5‐dibromophenyl)methanamine, and PEG macromonomer were coupled with 1,4‐benzenediboronic acid in a similar
我们报告的多官能共轭聚合物的制造的新方法,即聚(p亚苯基)S(购买力平价)具有多肽(聚升赖氨酸,PLL)和亲水性聚(乙二醇)(PEG)侧链。该方法由Suzuki耦合和原位N的组合组成-羧酸酐(NCA)开环聚合(ROP)工艺。首先,使用(2,5-二溴苯基)甲胺作为引发剂,通过相应NCA前体的ROP制备多肽大分子单体。在钯催化剂的存在下,使用1,4-苯二硼酸作为偶联伙伴,将获得的具有二溴苯末端官能团的多肽和PEG大分子单体进行Suzuki偶联反应,得到所需的聚合物。还采用相同程序的不同顺序来产生具有基本相同结构的聚合物。在反向序列模式下,低摩尔质量的单体(2,5-二溴苯基)甲胺和PEG大分子单体与1,4-苯二硼酸以类似方式偶联,然后通过伯氨基将L-赖氨酸NCA前体进行ROP所得的聚亚苯基。©2015 Wiley Periodicals,Inc.
