具有精确形态和尺寸控制的分级纳米结构的构建一直是当代材料科学和化学的最终目标之一，并且使用人工构建块来模拟在自然界中实现的量身定制的纳米级超结构，构成了突出的挑战。在此，我们报道了一种从液晶嵌段共聚物通过原位引发-生长过程精确合成分级纳米结构的一锅法策略。组装过程类似于活性链聚合，可以由小分子、大分子甚至纳米物体引发剂引发，以产生具有高度均匀形态和精细可调尺寸的各种分层超结构。由于高度的可控性和可预测性，这种组装策略为设计和构建具有广泛实用性和可访问性的分层结构开辟了道路。
The construction of hierarchical nanostructures with precise morphological and dimensional control has been one of the ultimate goals of contemporary materials science and chemistry, and the emulation of tailor-made nanoscale superstructures realized in the nature, using artificial building blocks, poses outstanding challenges. Herein we report a one-pot strategy to precisely synthesize hierarchical nanostructures through an in-situ initiation-growth process from a liquid crystalline block copolymer. The assembly process, analogous to living chain polymerization, can be triggered by small-molecule, macromolecule or even nanoobject initiators to produce various hierarchical superstructures with highly uniform morphologies and finely tunable dimensions. Because of the high degree of controllability and predictability, this assembly strategy opens the avenue to the design and construction of hierarchical structures with broad utility and accessibility.
