Anisotropic Nanostructures(#br)In article number 2300688, Yun Yan, Haibing Wei, Qingrong Qian, Jie Zhang, and co‐workers report an exquisite crystallization‐directed ionic self‐assembly (CDISA) to build size‐controllable anisotropic nanostructures via a hierarchical self‐assembly process, involving a requisite aqueous pre‐assembly to micelles and a subsequent evaporation‐induced self‐assembly to nanoprisms. The formation of anisotropic nanostructures derives from the crystalline polyethylene oxide (PEO) segments which endow ionic system with self‐assembling orientation. Length and width of the obtained nanoprisms can be facilely tuned by simply varying the initial concentration of the micellar solution.
