Reverse Sequence Polymerization-Induced Self-Assembly in Aqueous Media. [PDF]

Angew Chem Int Ed Engl, 2022
AbstractWe report a new aqueous polymerization‐induced self‐assembly (PISA) formulation that enables the hydrophobic block to be prepared first when targeting diblock copolymer nano‐objects. This counter‐intuitive reverse sequence approach uses an ionic reversible addition–fragmentation chain transfer (RAFT) agent for the RAFT aqueous dispersion ...

RAFT‐Mediated Polymerization‐Induced Self‐Assembly [PDF]

Angewandte Chemie International Edition, 2020
AbstractAfter a brief history that positions polymerization‐induced self‐assembly (PISA) in the field of polymer chemistry, this Review will cover the fundamentals of the PISA mechanism. Furthermore, this Review will also give an overview of some of the features and limitations of RAFT‐mediated PISA in terms of the choice of the components involved ...

Polymerization-induced thermal self-assembly (PITSA) [PDF]

Chemical Science, 2015
Polymerization-induced self-assembly (PISA) is a versatile technique to achieve a wide range of polymeric nanoparticle morphologies. Most previous examples of self-assembled soft nanoparticle synthesis by PISA rely on a growing solvophobic polymer block ...

Predicting Monomers for Use in Polymerization‐Induced Self‐Assembly [PDF]

Angewandte Chemie International Edition, 2018
AbstractWe report an in silico method to predict monomers suitable for use in polymerization‐induced self‐assembly (PISA). By calculating the dependence of LogPoct /surface area (SA) on the length of the growing polymer chain, the change in hydrophobicity during polymerization was determined.

Self-Assembling Peptide—Polymer Nano-Objects via Polymerization-Induced Self-Assembly [PDF]

Macromolecules, 2020
Self-assembling peptides (SAPs) have been extensively studied for their ability to form nanoscale ordered structures driven by noncovalent molecular interactions. Meanwhile, polymerization-induced self-assembly (PISA) has been exploited as a facile and efficient way to produce various amphiphilic block copolymer nano-objects, whose self-assembly was ...
