Liquid-Crystallization-Driven Self-Assembly toward Uniform Multi-Morphology Fried-Egg-Like Nanostructures.

Liquid-crystallization-driven self-assembly (LCDSA) has recently emerged as an efficient strategy to create uniform one-dimensional (1-D), 2-D and 3-D nanostructures in a controlled manner. However, the examples of generation of uniform multi-morphology nanostructures from solution self-assembly of one single polymer sample are rare. Herein, we report the first example of preparation of multi-morphology fried-egg-like nanostructures consisting of an inner spherical/bowl-like core of uniform size and platelets protruded from the core by LCDSA of PAMAM-Azo (PAMAM=polyamidoamine, Azo=azobenzene) in methanol.
