Involving supramolecular chemistry in self‐assembling block copolymer systems enables design of complex macromolecular architectures that, in turn, could lead to complex phase behavior. It is an elegant route, as complicated and sensitive synthesis techniques can be avoided. Highly grafted double‐comb diblock copolymers based on symmetric double hydrogen bond accepting poly(4‐vinylpyridine)‐block‐poly(N‐acryloylpiperidine) diblock copolymers and donating 3‐nonadecylphenol amphiphiles are realized and studied systematically by changing the molecular weight of the copolymer. Double perpendicular lamellae‐in‐lamellae are formed in all complexes, independent of the copolymer molecular weight. Temperature‐resolved measurements demonstrate that the supramolecular nature and ability to crystallize are responsible for the formation of such multiblock‐like structures. Because of these driving forces and severe plasticization of the complexes in the liquid crystalline state, this supramolecular approach can be useful for steering self‐assembly of both low‐ and high‐molecular‐weight block copolymer systems.

高接枝对称超分子双梳二嵌段共聚物中分层结构形成的起源
将超分子化学引入自组装嵌段共聚物体系中，可以设计复杂的大分子结构，进而可能导致复杂的相行为。这是一条优雅的路线，因为可以避免复杂而敏感的合成技术。高度接枝的接受聚（4-乙烯基吡啶）的基础上对称双氢键双梳二嵌段共聚物-嵌段-聚（Ñ -acryloylpiperidine）二嵌段共聚物和捐赠3- nonadecylphenol两亲物来实现，并通过改变共聚物的分子量系统的研究。双垂直lamellae-在在所有复合物中均会形成薄片，而与共聚物的分子量无关。温度分辨的测量表明，超分子性质和结晶能力是造成这种多嵌段状结构的原因。由于这些驱动力和液晶态配合物的严重塑化，这种超分子方法可用于控制低分子量和高分子量嵌段共聚物体系的自组装。
