This article provides an overview of recent simulation investigations of the nanostructures and structure–property relationships in copolymer systems.
Conventional fluorophore-free dual pH- and thermo-responsive luminescent alternating copolymer
Herein, we have designed and synthesized a novel traditional fluorophore-free water-soluble fluorescent copolymer based on a poly(maleimide-alt-styrene) skeleton, which responds to both pH and temperature in aqueous medium.
Surface-initiated polymerization-induced self-assembly of bimodal polymer-grafted silica nanoparticles towards hybrid assemblies in one step
The first case of surface-initiated polymerization-induced self-assembly (SI-PISA) by polymerizing benzyl methacrylate from SiO2-g-(PHEMA, CPDB) in methanol is reported.
Room temperature phosphorescence of 4-bromo-1,8-naphthalic anhydride derivative-based polyacrylamide copolymer with photo-stimulated responsiveness
Room temperature phosphorescence emission was achieved by host–guest recognition between γ-cyclodextrin and a 4-bromo-1,8-naphthalic anhydride polymer, which can be controlled by the photo-isomerization of the azobenzene unit of the other polymer.
Microwave-assisted synthesis of block copolymer nanoparticles via RAFT with polymerization-induced self-assembly in methanol
A comparative study of microwave-assisted (MA) and conductive heating in RAFT dispersion polymerization formulations in MeOH that result in polymerization-induced self-assembly is detailed.

Here we construct the first pillararene-based amphiphilic supramolecular brush copolymer, which can be utilized as a targeting self-imaging drug delivery vehicle.
Synthesis of zwitterionic, hydrophobic, and amphiphilic polymers via RAFT polymerization induced self-assembly (PISA) in acetic acid
Hydrophilic, hydrophobic, and combinations of these monomers were directly (co)polymerized via RAFT polymerization induced self-assembly (PISA) in acetic acid.

A novel fluorescent monomer was synthesized to probe the state of CO2-responsive cross-linked polymer particles.
Salicylaldehyde-functionalized block copolymer nano-objects: one-pot synthesis via polymerization-induced self-assembly and their simultaneous cross-linking and fluorescence modification
Salicylaldehyde-functionalized nano-objects are prepared via RAFT-mediated polymerization-induced self-assembly. Their simultaneous stabilization and fluorescence modification can be achieved by one-step reaction.
Unanticipated bright blue fluorescence produced from novel hyperbranched polysiloxanes carrying unconjugated carbon–carbon double bonds and hydroxyl groups
Bright blue fluorescence-emitting hyperbranched polysiloxane simultaneously carrying unconjugated carbon–carbon double bonds and hydroxyl groups is reported for the first time.
Disk-like micelles with cylindrical pores from amphiphilic polypeptide block copolymers
An unprecedented 2-dimensional disk-like micelle with cylindrical pores was achieved by self-assembly of amphiphilic block copolypeptides PEG-b-PBLG with an α-helical conformation of PBLG blocks.
Room temperature synthesis of poly(poly(ethylene glycol) methyl ether methacrylate)-based diblock copolymer nano-objects via Photoinitiated Polymerization-Induced Self-Assembly (Photo-PISA)
A remarkably diverse set of complex polymer nanoparticle morphologies have been prepared by photoinitiated polymerization-induced self-assembly (photo-PISA) at room temperature.

Synthesis, characterisation and Pickering emulsifier performance of poly(stearyl methacrylate)–poly(N-2-(methacryloyloxy)ethyl pyrrolidone) diblock copolymer nano-objects via RAFT dispersion polymerisation in n-dodecane
Block copolymer spheres, worms or vesicles can be prepared via RAFT dispersion polymerisation of N-(methacryloyloxy)ethyl pyrrolidone in n-dodecane using a poly(stearyl methacrylate) chain transfer agent.
Multicompartment morphologies self-assembled from fluorinated ABC triblock terpolymers: the effects of flexible and rigid hydrophobic moieties
Two kinds of fluorinated ABC triblock terpolymers have been prepared by oxyanion-initiated polymerization, and the effects of flexible and rigid polyolefin moieties on their self-assembled multicompartment morphologies were investigated.

Addition of water to an alcoholic RAFT PISA formulation leads to faster kinetics but limits the evolution of copolymer morphology
Addition of water leads to a much faster rate for the RAFT dispersion polymerization of benzyl methacrylate in ethanol, enabling degrees of polymerization of up to 1500 to be achieved.
