Natural, including plant, and synthetic phenolic acids are employed as building blocks for the synthesis of constitutional isomeric libraries of self-assembling dendrons and dendrimers that are the simplest examples of programmed synthetic macromolecules. Amphiphilic Janus dendrimers are synthesized from a diversity of building blocks including natural phenolic acids. They self-assemble in water or buffer into vesicular dendrimersomes employed as biological membrane mimics, hybrid and synthetic cells. These dendrimersomes are predominantly uni- or multilamellar vesicles with size and polydispersity that is predicted by their primary structure. However, in numerous cases, unilamellar dendrimersomes completely free of multilamellar assemblies are desirable. Here, we report the synthesis and structural analysis of a library containing 13 amphiphilic Janus dendrimers containing linear and branched alkyl chains on their hydrophobic part. They were prepared by an optimized iterative modular synthesis starting from natural phenolic acids. Monodisperse dendrimersomes were prepared by injection and giant polydisperse by hydration. Both were structurally characterized to select the molecular design principles that provide unilamellar dendrimersomes in higher yields and shorter reaction times than under previously used reaction conditions. These dendrimersomes are expected to provide important tools for synthetic cell biology, encapsulation, and delivery.

基于天然酚酸的两亲性Janus树状聚合物的筛选，以发现单分散的单层树状聚合物。

天然的，包括植物的和合成的酚酸被用作合成自组装树突和树状聚合物的构成异构体文库的结构单元，所述自组装树突和树状大分子是编程的合成大分子的最简单实例。两亲性Janus树状大分子由包括天然酚酸在内的多种结构单元合成而成。它们在水中或缓冲液中自组装成囊状树状小体，用作生物膜模拟物，杂种和合成细胞。这些树状小体主要是单层或多层囊泡，其大小和多分散性由其一级结构预测。然而，在许多情况下，理想的是完全没有多层组件的单层树状大分子体。这里，我们报告的库的合成和结构分析，该库包含13个两亲性Janus树状大分子，其疏水部分包含线性和分支烷基链。它们是通过从天然酚酸开始的优化的迭代模块合成制备的。通过注射制备单分散的树枝状小体，通过水合制备大分散的大分子。两者的结构特征都在于选择分子设计原理，该原理可提供比以前使用的反应条件更高的产率和更短的反应时间的单层树状大分子体。这些树状大分子有望为合成细胞生物学，封装和递送提供重要的工具。它们是通过从天然酚酸开始的优化的迭代模块合成制备的。通过注射制备单分散的树枝状小体，通过水合制备大分散的大分子。两者的结构特征都在于选择分子设计原理，该原理可提供比以前使用的反应条件更高的产率和更短的反应时间的单层树状大分子体。这些树状大分子有望为合成细胞生物学，封装和递送提供重要的工具。它们是通过从天然酚酸开始的优化的迭代模块合成制备的。通过注射制备单分散的树枝状小体，通过水合作用形成大的多分散体。两者的结构特征都在于选择分子设计原理，该原理可提供比以前使用的反应条件更高的产率和更短的反应时间的单层树状大分子体。这些树状大分子有望为合成细胞生物学，封装和递送提供重要的工具。
