Tailored 2D Hierarchical Architectures via Interfacial Living Supramolecular Polymerization for Enhanced Exciton Migration

open access: yesAggregate
The structural precision of living supramolecular polymerization processes is dictated by nucleation control, conventionally achieved through kinetic trapping of monomers in metastable aggregates or inactive molecular states.

Chemical fuel-driven living and transient supramolecular polymerization

open access: yesNature Communications, 2019
Temporal control over self-assembly processes is a desirable trait for discovering adaptable and controllable materials. Here the authors show that a chemical fuel driven system can not only self-assemble in a controlled manner, but can also result in ...

In-situ syntheses of graft copolymers by metal-free strategies: combination of photoATRP and ROP

open access: yesDesigned Monomers and Polymers, 2020
A completely metal-free and environmentally friendly strategy is demonstrated for the preparation of graft copolymers by combining photoinduced Atom Transfer Radical Polymerization (ATRP) and Ring Opening Polymerization (ROP).

Oriented arrangement of simple monomers enabled by confinement: towards living supramolecular polymerization

open access: yesNature Communications, 2021
Using simple monomers in living supramolecular polymerization is difficult due to energy principles. Here the authors use confinement from a layered double hydroxide nanomaterial to successfully polymerise several simple monomers with length control and ...

Anionic polymerization of p-(2,2′-diphenylethyl)styrene and applications to graft copolymers

open access: yesDesigned Monomers and Polymers, 2017
Well-controlled anionic polymerization of an initiator-functionalized monomer, p-(2,2′-diphenylethyl)styrene (DPES), was achieved for the first time. The polymerization was performed in a mixed solvent of cyclohexane and tetrahydrofuran (THF) at 40 °C ...

Ionic living polymerization

open access: yesPolimery, 2002
A review of research works on ionic living polymerization, published mainly in recent years, has been presented. In majority the publications concern anionic polymerization of methacrylates and acrylates, however living polymerization has been investigated also for vinyl monomers as well as for heterocyclic ones (ring opening polymerization).

Photoinduced Synthesis of Block Copolymers by Combination of Atom Transfer Radical Polymerization and Photoinduced Radical Oxidation/Addition/Deactivation

open access: yesJournal of the Turkish Chemical Society, Section A: Chemistry, 2018
A new polymerization mechanistic transformation strategy, combining two different controlled polymerization techniques of different modes, atom transfer radical polymerization (ATRP) and photoinduced radical oxidation/addition/deactivation (PROAD), is ...

Surface-initiated Atom Transfer Radical Polymerization and Solution Intercalation Methods for Preparation of Cellulose-G-PS-G-PAN/MMT Bionanocomposite [PDF]

open access: yesJournal of Petroleum Science and Technology, 2017
Cellulose was modified by polystyrene (PS) and polyacrylonitrile (PAN) via free radical and living radical polymerization, and then cellulose was used as the matrix in the preparation of polymer/clay nanocomposite, through a solution intercalation method.

Living Ring-Opening Polymerization of O-Carboxyanhydrides: The Search for Catalysts

open access: yesFrontiers in Chemistry, 2018
Biodegradable poly(α-hydroxy acids) can be synthesized by means of ring-opening polymerization (ROP) of O-carboxyanhydrides (OCAs). Numerous catalysts have been developed to control the living polymerization of OCAs.
