Recently proposed novel nanoarchitectonics concept is based on the unification of nanotechnology and other constructive sciences such as supramolecular chemistry including self-assembly/self-organization to provide the functional nanostructures and materials through architecting efforts of nano-sized components. In this short review, we focus on the structural changes and related dynamic functions with the terminology of dynamic nanoarchitectonics. We will cover selected topics on supramolecular polymorphism, supramolecular differentiation and dynamic-motion-based functions. Such phenomena have been observed in shape-diverse assemblies of amphiphilic tripeptides, polymorphisms in assemblies and crystals of fullerene derivatives such as supramolecular differentiation for the spontaneous growth of tails (tubes) from the egg of fullerene assemblies. Similarly, they have also been realized in self-propelled nano- and micromotors and robots, self-powered cargo delivery system with several bio and supramolecular components, manipulation of liquid slugs within photoactive tubular microactuators, materials with ameba-like motions through autonomous periodic sol-gel transition, molecular machine regulation by hand-motion-like macroscopic actions (hand-operating nanotechnology) and mechanical tuning for molecular receptors functions. These examples inspire us to create new functional materials with truly life-like activities through nanoarchitecting simple nano/molecular units.

动态纳米建筑学:超分子多态性和分化,变形器和手动纳米技术

最近提出的新颖的纳米建筑学概念是基于纳米技术和其他建设性科学的结合,例如超分子化学,包括自组装/自组织,以通过设计纳米尺寸的组件来提供功能性的纳米结构和材料。在这篇简短的评论中,我们关注动态纳米建筑学术语的结构变化和相关的动态功能。我们将涵盖有关超分子多态性,超分子分化和基于动态运动的功能的精选主题。在两亲性三肽的形状多样的组装体,组装体的多态性和富勒烯衍生物的晶体(例如超分子分化)中观察到了这种现象,以自富勒烯组装体的卵自发生长尾巴(管)。类似地,它们也已经在以下方面实现了:自动纳米和微型电动机和机器人,带有几种生物和超分子组件的自供电货物输送系统,在光敏管状微致动器内操纵液团,通过自主的周期性溶胶具有类似ameba的运动的材料-凝胶转变,通过类似手动作的宏观动作(手动纳米技术)进行分子机器调节以及对分子受体功能的机械调节。这些实例启发我们通过纳米结构简单的纳米/分子单元来创造具有真正逼真的活动的新型功能材料。操纵光敏管状微致动器中的液体团块,通过自主的周期性溶胶-凝胶转变而具有类似ameba的运动的材料,通过类似手运动的宏观作用(手动纳米技术)进行分子机器调节以及对分子受体功能的机械调节。这些实例启发我们通过纳米结构简单的纳米/分子单元来创造具有真正逼真的活动的新型功能材料。操纵光敏管状微致动器中的液体团块,通过自主的周期性溶胶-凝胶转变而具有类似ameba的运动的材料,通过类似手运动的宏观作用(手动纳米技术)进行分子机器调节以及对分子受体功能的机械调节。这些实例启发我们通过纳米结构简单的纳米/分子单元来创造具有真正逼真的活动的新型功能材料。
