树枝状和线性聚合物结构在同一个大分子中的组合开辟了新的可能性，为嵌段共聚物的设计和具有自组装性能的功能聚合物的应用。线性-树枝状嵌段共聚物（LDBC）的合成有三种主要策略，特别是点击化学的出现使得预形成的嵌段的偶联成为获得LDBC文库的最有效的方法之一。在这些材料中，树突的外围可以被精确地功能化，以获得在不同技术领域具有感兴趣的自组装特性的功能LDBC。刺激响应部分的掺入产生智能材料，其通常被加工为具有可以由外部刺激控制的形态的两亲性LDBC的自组装体。特别强调的是光响应LDBC。此外，简要回顾了LDBCs在生物医学或材料科学方面的应用。
The combination of dendritic and linear polymeric structures in the same macromolecule opens up new possibilities for the design of block copolymers and for applications of functional polymers that have self-assembly properties. There are three main strategies for the synthesis of linear-dendritic block copolymers (LDBCs) and, in particular, the emergence of click chemistry has made the coupling of preformed blocks one of the most efficient ways of obtaining libraries of LDBCs. In these materials, the periphery of the dendron can be precisely functionalised to obtain functional LDBCs with self-assembly properties of interest in different technological areas. The incorporation of stimuli-responsive moieties gives rise to smart materials that are generally processed as self-assemblies of amphiphilic LDBCs with a morphology that can be controlled by an external stimulus. Particular emphasis is placed on light-responsive LDBCs. Furthermore, a brief review of the biomedical or materials science applications of LDBCs is presented.
