One of the greatest challenges in colloidal self-assembly is to obtain multiple distinct but transformable suprastructures from the same particles in monophasic solvent. Here, we combined deformable and rigid lobes in snowman-shaped amphiphilic Janus nanoparticles (JNPs). These JNPs exhibited excellent ability to self-assemble into micelles, worms, mini-capsules, giant- and elongated-vesicles. This rich suprastructural diversity was obtained by kinetic manipulation of the self-assembly conditions. The suprastructures consist of four to thousands of highly oriented JNPs with dimensions ranging from 500-nanometer to 30-μm. Moreover, the suprastructures can be transformed into one another or dissembled into individual particles. These features make colloidal assembly highly comparable to that of amphiphilic molecules, however, key differences were discovered.

Janus纳米粒子的自组装成可变换的超结构。
胶体自组装的最大挑战之一是从单相溶剂中的相同颗粒中获得多个不同但可转化的超结构。在这里，我们在雪人形状的两亲Janus纳米粒子（JNPs）中结合了可变形和刚性的裂片。这些JNP表现出出色的自组装成胶束，蠕虫，微型胶囊，巨型和细长囊泡的能力。这种丰富的超结构多样性是通过自组装条件的动力学操纵获得的。超结构由四到数千个高度定向的JNP组成，尺寸从500纳米到30微米不等。此外，超结构可以彼此转化或分解成单个颗粒。这些特征使胶体组装与两亲分子具有高度的可比性，但是，
