Hierarchical ultrathin nanoarchitectures are structurally stable and functionally versatile, which are supramolecular building blocks with a broad range of applications from optoelectronic devices to tunable biosensors. Here, we present a facile and scalable strategy to fabricate an ultrathin polymer nanoarchitecture with islands of alkyl chains for spontaneous interfacial molecular orientation by using the hierarchical and automatic self-assembly of amphiphilic comb-like copolymers. The intriguing self-constructed nanoarchitecture is achieved by facile doping and interfacial self-assembly of amphiphilic poly(dodecyl acrylate)–poly(acrylic acid) comb-like copolymers on hydrophilic indium tin oxide substrate. It is experimentally revealed that an ultrathin and spiky polymer nanoarchitecture with a hydrophobic segment surface formed by hydrophilic and cooperative interactions of amphiphilic copolymers ensures an automatic vertical molecular alignment of liquid crystals during hierarchical self-construction process. Furthermore, this effective approach affords a fast responsive and low-voltage driving polymer nanoarchitecture with an enhanced electro-optical performance compared to common polyimide layer.

分层超薄纳米结构在结构上稳定且功能多样，是超分子构建块，具有从光电器件到可调生物传感器的广泛应用。在这里，我们提出了一种简便且可扩展的策略，通过使用两亲梳状共聚物的分级和自动自组装来制造具有烷基链岛的超薄聚合物纳米结构，用于自发界面分子取向。有趣的自构建纳米结构是通过在亲水性氧化铟锡基底上轻松掺杂和界面自组装两亲性聚（丙烯酸十二烷基酯）-聚（丙烯酸）梳状共聚物来实现的。实验表明，由两亲共聚物的亲水性和协同相互作用形成的具有疏水链段表面的超薄和尖刺聚合物纳米结构确保了液晶在分层自构建过程中的自动垂直分子排列。此外，与普通聚酰亚胺层相比，这种有效的方法提供了一种快速响应和低电压驱动的聚合物纳米结构，具有增强的电光性能。
