“…The performance of fuel cells exhibits the highest initial transport efficiency and high durability when the aspect ratio of mesoporous carbon particles is 6.2 (Figure 8e). 37 Furthermore, Zhu's group 38,39 has developed a facile and versatile route to prepare anisotropic mesoporous carbon particles by combining BCP emulsion selfassembly with the strategy of self-templated direct carbonization. This route introduces an effective concept to obtain functional speciesloaded and N-doped mesoporous carbon particles, which broadens the boundary of BCP particles in application of fuel cells.…”

The self‐assembly of block copolymers (BCPs) within emulsion droplets is a flexible strategy for the preparation of polymer particles. This strategy permits the fine‐tuning of shapes, internal structures, and surface nanostructures of the polymer particles, thus allowing many applications. Although some literature has reviewed the BCP preparation via self‐assembly within a droplet, a comprehensive summary including in‐depth understanding, controllable preparation, and application is lacked. In this review, we systematically delve into the multiple mechanisms that drive BCP self‐assembly within emulsion droplets, such as commensurability effects for minimizing total free energy, interfacial instability, organized spontaneous emulsification, phase separation of multiple components, and entropy effects between BCPs and nanoparticles. Additionally, a strategy combining selective cross‐linking and disassembly can further generate Janus particles featuring unique structures. Next, various applications across multiple disciplines are discussed, including drug delivery, display, biomedical imaging, macromolecular separation, and fuel cells. Finally, we present an overview of the current challenges and future directions for BCP emulsion self‐assembly, covering mechanism investigation, molecular design, stability control, and application exploration. We anticipate deeper understanding, more varieties, enhanced performance, and broader applications can be achieved with BCP emulsion self‐assembly after addressing the challenge.

“…Polymeric assemblies including spherical, star-like, or worm-like nanoparticles, vesicles, or other complex structures could perform numerous applications in drug carriers or nanoreactors because of their unique characteristics and stability in a water environment. − The self-assembly of amphiphilic copolymers with both hydrophilic and hydrophobic building blocks have been studied extensively, and several ripe experiences have been summarized. However, besides amphiphilic copolymers, covalently linked organic–inorganic hybrid materials bearing organic polymer chains and inorganic units, such as carbon or metal nanoparticles, have attracted a lot of research interest. − Among inorganic nanobuilding blocks, polymer chain-modified fullerene C 60 has been widely investigated. − As one of the typical examples, a series of supramolecular nanoassemblies, including the core–shell structure, spherical nanoparticles (SNPs), and nanonetwork architectures could be constructed from isotactic (it-) and syndiotactic (st-) C 60 -end-capped poly(methyl methacrylate)s through adjusting the types of solvents and block ratios …”

Supramolecular assembly has attracted significant attention and has been applied to various applications. Herein, a β−γ-CD dimer was synthesized to complex different guest molecules, including single-strand polyethylene glycol (PEG)modified C 60 (PEG-C 60 ), photothermal conversion reagent (IR780), and dexamethasone (Dexa), according to the complexation constant-dependent specific selectivity. Spherical or cylindrical nanoparticles, monolayer or bilayer vesicles, and bilayer fusion vesicles were discovered in succession if the concentration of PEG-C 60 was varied. Moreover, if near-infrared light was employed to irradiate these nanoassemblies, the thermo-induced morphological evolution, subsequent cargo release, photothermal effect, and singlet oxygen ( 1 O 2 ) generation were successfully achieved. The in vitro cell experiments confirmed that these nanoparticles possessed excellent biocompatibility in a normal environment and achieved superior cytotoxicity by light regulation. Such proposed strategies for the construction of multilevel structures with different morphologies can open a new window to obtain various host−guest functional materials and achieve further use for disease treatment.

Three‐dimensional confined self‐assembly (3D‐CSA) of block copolymers (BCPs) is a distinctive and robust strategy that can yield colloidal polymer particles boasting ordered internal structures and diverse morphologies. The unique advantage of neutral interface lies in its ability to create anisotropic particles with surface patterns. The resulting unique polymer particles exhibit deformability under swelling, coupled with excellent spreadability and optical properties. These particles can also be used for fabrication of anisotropic nanoobjects or mesoporous particles via disassembly or serving as templates. This review comprehensively outlines the research advancements in neutral interface‐guided 3D‐CSA systems, including surfactant engineering, internal structure control, properties and future possibilities of anisotropic patterned particles.
