Single-Step Expeditious Synthesis of Diblock Copolymers with Different Morphologies by Lewis Pair Polymerization-Induced Self-Assembly.

Angewandte Chemie, 2022
Lewis pair polymerization has demonstrated its uniuqe advantages and powerful capability in polymer synthesis. Here we employ strong nucleophilic N -heterocyclic olefin (NHO) and bulky organoaluminum to construct frustrated Lewis pair, which can realize ...

Photo-PISA: Shedding Light on Polymerization-Induced Self-Assembly.

ACS Macro Letters, 2015
Herein we report an aqueous photoinitiated polymerization-induced self-assembly (photo-PISA) for the preparation of a remarkably diverse set of complex polymer nanoparticle morphologies (e.g., spheres, worms, and vesicles) at room temperature. Ultrafast polymerization rates were achieved, with near quantitative monomer conversion within 15 min of ...

Reactive and Functional Nanoobjects by Polymerization‐Induced Self‐Assembly

Macromolecular Rapid Communications, 2018
AbstractPolymerization‐induced self‐assembly (PISA) is becoming a standard technique for generating core–shell polymeric nanoparticles of various morphologies ranging from classic spheres to rods/fibers (“worm‐like”) and vesicles. After the initial quest for polymerization control in dispersed media, the focus of PISA research has drastically shifted ...

Direct Access to Polysaccharide-Based Vesicles with a Tunable Membrane Thickness in a Large Concentration Window via Polymerization-Induced Self-Assembly.

Biomacromolecules, 2021
Polymersomes are multicompartmental vesicular nano-objects obtained by self-assembly of amphiphilic copolymers. When prepared in the aqueous phase, they are composed of a hydrophobic bilayer enclosing water.
