Kinetics‐Regulated Interfacial Selective Superassembly of Asymmetric Smart Nanovehicles with Tailored Topological Hollow Architectures

Abstract

Hollow nanoparticles featuring tunable structures with spatial and chemical specificity are of fundamental interest. However, it remains a significant challenge to design and synthesize asymmetric nanoparticles with controllable topological hollow architecture. Here, a versatile kinetics‐regulated cooperative polymerization induced interfacial selective superassembly strategy is demonstrated to construct a series of asymmetric hollow porous composites (AHPCs) with tunable diameters, architectures and components. The size and number of patches on Janus nanoparticles can be precisely manipulated by the precursor and catalyst content. Notably, AHPCs exhibit excellent photothermal conversion performance under the irradiation of a near infrared (NIR) laser. Thus, AHPCs are utilized as NIR light‐triggered nanovehicles and cargos can be controllably released. In brief, this versatile superassembly approach offers a streamlined and powerful toolset to design diverse asymmetric hollow porous composites.

“…For example, Kong et al synthesized a fuel-free nanomotor for optical drive propulsion in the near-infrared using a dynamically-controlled competitive nucleation and assembly of asymmetric porous and hollow carbon on solid SiO 2 and polystyrene (PS) templates. 17,18 Caruso et al developed a versatile supramolecular complexation strategy for synthesizing diverse particles with hollow and yolk-shell structures using tannic-acid-stabilized poly(benzene-1,4-dithiol) template particles. 19 However, the main disadvantage of the hard template method is the tedious template removal process, which greatly increases the operational complexity and energy consumption.…”
