“…Following the elegant studies of crystallization-driven block copolymer self-assembly reported by Manners and Winnik [80][81][82][83][84][85], PISA syntheses of diblock copolymer nano-objects with semi-crystalline cores have been recently reported in the literature. For example, Charleux and co-workers conducted the RAFT dispersion polymerization of a bespoke cholestryl-based (meth)acrylic core-forming monomer in an ethanol/water mixture to produce well-defined diblock copolymer nanorods and nanofibers [44].…”

There is considerable current interest in polymerization-induced self-assembly (PISA) via reversible addition-fragmentation chain transfer (RAFT) polymerization as a versatile and efficient route to various types of block copolymer nano-objects. Many successful PISA syntheses have been conducted in water using either RAFT aqueous dispersion polymerization or RAFT aqueous emulsion polymerization. In contrast, this review article is focused on the growing number of RAFT PISA formulations developed for non-aqueous media. A wide range of monomers have been utilized for both the stabilizer and core-forming blocks to produce diblock copolymer nanoparticles in either polar or non-polar solvents via RAFT dispersion polymerization. Such nanoparticles can exhibit spherical, worm-like or vesicular morphologies, often with controllable size and functionality. Detailed characterization of such sterically-stabilized diblock copolymer dispersions provide important insights into the various morphological transformations that can occur both during the PISA synthesis and also subsequently on exposure to a suitable external stimulus (e.g. temperature).

“…380 Furthermore, cylindrical micelles of controlled length (L n 5 72-320 nm) and low dispersity ( -D 5 1.02-1.08) with p-conjugated crystalline cores were obtained via the CDSA of poly(3-hexylthiophene)-block-poly(dimethylsiloxane) (P3HT-b-PDMS) in hexane or diethylether using seed micelles as initiators. 381 Next to the single component micelles, B-A-B triblock comicelles were obtained by CDSA using P3HT-b-PS unimers for the A block, and P3HT-b-PDMS for the B block in the multicomponent cylindrical micelles. 382 Hayward and coworkers reported the sonocrystallization of a twocomponent mixture of a perylene diimide (PDI) derivative with P3HT, which acts as a soluble crystal modifier.…”

The self-assembly into supramolecular polymers is a process driven by reversible non-covalent interactions between monomers, and gives access to materials applications incorporating mechanical, biological, optical or electronic functionalities. Compared to the achievements in precision polymer synthesis via living and controlled covalent polymerization processes, supramolecular chemists have only just learned how to developed strategies that allow similar control over polymer length, (co)monomer sequence and morphology (random, alternating or blocked ordering). This highlight article discusses the unique opportunities that arise when coassembling multicomponent supramolecular polymers, and focusses on four strategies in order to control the polymer architecture, size, stability and its stimuli-responsive properties: (1) endcapping of supramolecular polymers, (2) biomimetic templated polymerization, (3) controlled selectivity and reactivity in supramolecular copolymerization, and (4) living supramolecular polymerization. In contrast to the traditional focus on equilibrium systems, our emphasis is also on the manipulation of selfassembly kinetics of synthetic supramolecular systems. V C 2016

“…6−10 Another advantage of CDSA is the easily tuned composition of the obtained nanostructures, and the dual-component or multicomponent nanostructures with different morphologies can be formed via random or block cocrystallization of the polymers with similar crystallized moieties. 11 The crystallized blocks in these polymers can be composed of poly(ferrocenyl dimethylsilane) (PFDMS), 12 poly(3-hexylthiophene) (P3HT), 13,14 poly(ε-caprolactone) (PCL), 15,16 stereoregular polylactides (srPLA), 17,18 poly(ethylene oxide), 19 polyethylene (PE), 20 and polyacrylonitrile (PAN). 21 Most of these types of block polymers can only form one-dimensional cylindrical or wormlike crystalline-core micelles through the living CDSA method.…”

We reported the preparation of uniform square nanosheets with tunable size by the living crystallization-driven 2D self-assembly of hyperbranched poly(ether amine) capped with heptaisobutyl polyhedral oligomeric silsesquioxane (POSS). The nanosheets of HP1 containing both anthracene (AN) and POSS moieties in a solution of 1,4-dioxane and water can be fragmented after the melting of the POSS moieties upon heating and can be regenerated after the recrystallization of POSS moieties, which was confirmed by microdifferential scanning calorimetry (μDSC) and dynamic light scattering (DLS) studies and transmission electron microscopy (TEM) images. The obtained fragmented nanosheets (HP1-NSs) with a relatively small size were used as seeds for the 2D epitaxial living growth of HP1 unimers to fabricate uniform square nanosheets with tunable edge lengths from ∼0.5 to ∼4.5 μm, which is dependent on the unimer-to-seed ratio. Furthermore, dual-component nanosheets can also be obtained by random cocrystallization of HP1 with another type of hPEA capped with POSS and ferrocene (HP2). This crystallization-driven 2D self-assembly behavior of POSS-capped hPEA might provide potential significance in the preparation of functional nanosheets with different sizes and components, which could be further used as templates for inorganic nanosheets and 2D-platforms for metal nanoparticles.
