In this paper, we report the synthesis of several poly(propyl ether imine) dendrons and dendrimers. These dendrons and dendrimers were constructed by involving an ether as the linker component and an imine as the branching component. The divergent syntheses of dendrons and dendrimers were established with the aid of two alternate Michael addition reactions and two alternate reduction reactions in a
在本文中,我们报告了几种聚(丙醚亚胺)树枝状和树枝状聚合物的合成。这些树枝状和树枝状大分子是通过包含醚作为连接剂组分和亚胺作为支化组分而构建的。借助两个交替的迈克尔加成反应和两个交替的还原反应以四步迭代的合成顺序建立树枝状和树枝状大分子的不同合成。合成了多达三代的树枝状分子,并将某些树枝状分子连接到类苯环核上,从而获得了多达两代的树枝状聚合物,其树枝状聚合物在外围含有12个羧酸。发现以醚为核心的发散合成更容易,在每个单独的步骤中,均获得了良好的收率和优异的收率,并且获得了在外围具有多达16个羧酸的三代树枝状大分子。采用的合成顺序使我们可以在其外围安装醇,胺或羧酸。对羧酸封端的树枝状和树枝状大分子的细胞毒性进行了评估,尽管大多数树枝状和树枝状大分子都没有表现出可测量的细胞毒性,甚至高达100微克/毫升,具有苯并类核的第二代树枝状大分子也显示出轻度的毒性。浓度超过30微克/毫升。
