“…In order to explore the generality of the new seeded growth approach to shaped 2D assemblies that utilises homopolymers with charged terminal groups, we applied an analogous design strategy to a semicrystalline organic polymer, 37 poly(L-lactide) (PLLA). 19,38,39 Two homopolymers with phosphonium groups at a chain terminus were prepared, PLLA24 Fig.…”

“…The core polymer is chosen for its ability to initiate crystallization-driven selfassembly (CDSA) of cylindrical BCP micelles when unimer is added to the solution, and the corona must provide strong adhesion to the surface of the inorganic particle. Many BCPs consisting of a long soluble block attached to a shorter crystallizable block 21 are potential candidates for this approach. While CDSA has been reported for BCPs with poly (3-hexylthiophene) 22 , polylactide 23 , polycaprolactone 24 and polyethylene 25 as the crystallizable block, one has the greatest control over this kind of seeded growth for polyferrocenylsilane (PFS) BCPs.…”

A design strategy for the hierarchical fabrication of colloidal hybrid mesostructures

Advances in nanotechnology depend upon expanding the ability to create new and complex materials with well-defined multidimensional mesoscale structures. The creation of hybrid hierarchical structures by combining colloidal organic and inorganic building blocks remains a challenge due to the difficulty in preparing organic structural units of precise size and shape. Here we describe a design strategy to generate controlled hierarchical organic-inorganic hybrid architectures by multistep bottom-up self-assembly. Starting with a suspension of large inorganic nanoparticles, we anchor uniform block copolymer crystallites onto the nanoparticle surface. These colloidally stable multi-component particles can initiate the living growth of uniform cylindrical micelles from their surface, leading to three-dimensional architectures. Structures of greater complexity can be obtained by extending the micelles via addition of a second core-crystalline block copolymer. This controlled growth of polymer micelles from the surface of inorganic particles opens the door to the construction of previously inaccessible colloidal organic-inorganic hybrid structures.

“…[23] Enhanced ordering was only obtained at T m, 2 < T < T ODT (a fluid, but microphase-separated state), whereas shear alignment at T > T ODT was unsuccessful. Furthermore, rapid cooling of P4PA109k-48(3-NDP) 1.0 from T > T ODT resulted in a highly disordered structure ( Figure S8 (breakout), [31] Supporting Information), while a short thermal treatment at T m, 2 < T < T ODT of ≈1 h gave rise to the double perpendicular lamellar-in-lamellar morphology as depicted in Figure 3c. Such a thermal treatment was, however, not necessary for the two lowest molecular weight complexes (P4PA31k-47 and P4PA57k-47), because these double-combs are apparently sufficiently mobile during crystallization of 3-NDP's side chains.…”

Involving supramolecular chemistry in self‐assembling block copolymer systems enables design of complex macromolecular architectures that, in turn, could lead to complex phase behavior. It is an elegant route, as complicated and sensitive synthesis techniques can be avoided. Highly grafted double‐comb diblock copolymers based on symmetric double hydrogen bond accepting poly(4‐vinylpyridine)‐block‐poly(N‐acryloylpiperidine) diblock copolymers and donating 3‐nonadecylphenol amphiphiles are realized and studied systematically by changing the molecular weight of the copolymer. Double perpendicular lamellae‐in‐lamellae are formed in all complexes, independent of the copolymer molecular weight. Temperature‐resolved measurements demonstrate that the supramolecular nature and ability to crystallize are responsible for the formation of such multiblock‐like structures. Because of these driving forces and severe plasticization of the complexes in the liquid crystalline state, this supramolecular approach can be useful for steering self‐assembly of both low‐ and high‐molecular‐weight block copolymer systems.
