Abstract
The utilization of polymer crystallization to manipulate the self-assembly of polymeric amphiphiles in solution is gaining increasing attention for the design of anisotropic core-shell nanoparticles and even more complex hierarchical architectures. Notably, the living-crystallization-driven self-assembly (CDSA) method, which involves seeded growth, has emerged as an ambient temperature approach for creating low-dispersity nanomaterials such as one-dimensional (1D) cylinders and two-dimensional (2D) platelets. This technique offers predictable size control and facilitates the creation of segmented structures with spatially defined compositions and functionalities, and in this process the epitaxial crystallization is regarded as the intrinsic mechanism of living CDSA. For this context, in this Viewpoint, we delineate the key aspects of the living CDSA seeded growth method, with a particular emphasis on the mechanism of seeded heteroepitaxial growth employing crystalline cores with distinct chemistries from the polymer crystallization perspective. Revealing the in-depth mechanism of heteroepitaxial crystallization enables the expansion of the design of segmented nanoparticles where the core compositions and functionalities are spatially defined. Utilizing the chemically distinct compositions and polymer crystallization strategies, the synthetic processes of 2D hollow platelets with a unique architecture are also summarized, which are of special interest for soft matter.

Abstract
Poly(p-phenylenevinylene) (PPV) is a classic semiconducting π-conjugated polymer with outstanding optical and electronic properties, which shows important applications in the fields of optoelectronic, such as organic light-emitting diodes (OLEDs), organic solar cells (OSCs), and organic field-effect transistors (OFETs). In the working process of the device, the microstate of PPV decides its property. Therefore, it is significant to achieve ordered morphologies based on PPV at micro scale. Due to the long rigid backbone and large area of delocalized electron, PPV has a strong tendency towards ordered aggregation through intermolecular π-π interaction, and "rod-coil" type block copolymer (BCP) based on PPV with a corona chain to improve the solubility is always built for self-assembly in situ solution. However, obtaining regular PPV based micro-/nano-structures in a controllable and uniform form remains challenging. In this review, we summarize the progresses in constructing multi-dimensional regular self-assembly morphologies based on PPV BCPs and exploring the application potential of these delicate functional nanomaterials. The molecular design strategy and growth mechanism can be extended to regulate the aggregation state of functional semiconducting conjugated polymers, which is beneficial to improving their performance in application of microelectronics, optoelectronics, biology and so on.

Abstract
Liquid-crystallization-driven self-assembly (LCDSA) has recently emerged as an efficient strategy to create uniform one-dimensional (1-D), 2-D and 3-D nanostructures in a controlled manner. However, the examples of generation of uniform multi-morphology nanostructures from solution self-assembly of one single polymer sample are rare. Herein, we report the first example of preparation of multi-morphology fried-egg-like nanostructures consisting of an inner spherical/bowl-like core of uniform size and platelets protruded from the core by LCDSA of PAMAM-Azo6 (PAMAM=polyamidoamine, Azo=azobenzene) in methanol. It is disclosed that the different aggregation rates for PAMAM-Azo6 with varying contents of Azo units spontaneously separated nucleation and growth stages, which led to the formation of inner spherical/bowl-like cores ("seeds") firstly, followed by the formation of platelets protruded from the edges of inner core to give "imperfect" fried-egg-like nanostructures. Additional annealing of initially formed "imperfect" fried-egg-like micelles will promote the rearrangement of Azo units to give thermodynamically-favored "perfect" fried-egg-shaped micelles with a uniform dimension both in the core and whole structure. This work not only provides an efficient strategy to create uniform multi-morphology fried-egg-shaped nanostructures, but also reveals the essential impact of aggregation kinetics of liquid-crystalline-coil BCPs in the formation of multi-morphology nanostructures.

Abstract
Two-dimensional, size-tunable, water-dispersible particle micelles with spatially defined chemistries can be obtained by using "living" crystallization-driven self-assembly (CDSA) approach. Nevertheless, a major obstacle of crystalline particles in drug delivery application is the difficulty in accessing to cargo within crystalline cores. In the present work, we design four different types of biocompatible two-dimensional platelets with a crystalline poly(ε-caprolactone) (PCL) core, a hydrophobic poly(4-vinylprydine) (P4VP) segment, and a water dispersible poly(N,N-dimethyl acrylamide) (PDMA) block in ethanol by seeded growth method. Transferring those uniform platelets with tailored compositions to an aqueous solution in the presence of a hydrophobic drug leads to efficient encapsulation of the cargo in the P4VP segments via hydrophobic interactions. These drug-loaded platelets exhibit pH-responsive release behavior in aqueous media due to the protonated-deprotonated process of P4VP blocks in acidic and neutral solutions. This work provides initial insight into biocompatible PCL platelets with low dispersity and precise chemistry control in stimulus-responsive drug delivery fields.

Abstract
π-Conjugated-polymer-based nanofibers (CPNFs) of controlled length, composition and morphology are promising for a broad range of emerging applications in optoelectronics, biomedicine and catalysis, owing to the morphological merits of fiber-like nanostructures and structural attributes of π-conjugated polymers. Living crystallization-driven self-assembly (CDSA) of π-conjugated-polymer-containing block copolymers (BCPs) has emerged as an efficient strategy to prepare CPNFs with precise dimensional and structural controllability by taking advantage of the crystallinity of π-conjugated polymers. In this review, recent advances in the generation of CPNFs have been highlighted. The influence of the structure of π-conjugated-polymer-containing BCPs and experimental conditions on the CDSA behaviors, especially seeded growth and self-seeding processes of living CDSA, has been discussed in detail, aiming to provide an in-depth overview of living CDSA of π-conjugated-polymer-containing BCPs. In addition, the properties of CPNFs as well as their potential applications have been illustrated. Finally, we put forward the current challenges and research directions in the field of CPNFs.

Abstract
In this work, it is demonstrated for the first time that heterojunction nanowires, consisting of a gradient and segmented-like heterogeneous π-conjugated core with controllable length, composition and morphology, can be generated by co-self-seeding of oligo(p-phenylene vinylene) (OPV)- and oligo(p-phenylene ethynylene) (OPE)-containing block copolymers in spite of different chain lengths and molecular conformation for OPE and OPV. More importantly, based on the understanding of the formation of heterogeneous core by the co-self-seeding approach, a "heating/cooling" seeded growth route was developed, by which linear and branched heterojunction nanowires containing a segmented heterogeneous π-conjugated core of controlled length, composition and morphology can be obtained. This work provides a versatile platform to generate heterojunction nanowires with excellent controllability in length, composition, and morphology.

Abstract
The morphology of nanomaterials critically influences their biological interactions. However, there is currently a lack of robust methods for preparing non-spherical particles from biocompatible materials. Here, we combine 'living' crystallisation-driven self-assembly (CDSA), a seeded growth method that enables the preparation of rod-like polymer nanoparticles, with poly(2-oxazoline)s (POx), a polymer class that exhibits 'stealth' behaviour and excellent biocompatibility. For the first time, the 'living' CDSA process was carried out in pure water, resulting in POx nanorods with lengths ranging from ∼60 to 635 nm. In vitro and in vivo study revealed low immune cell association and encouraging blood circulation times, but little difference in the behaviour of POx nanorods of different length. The stealth behaviour observed highlights the promising potential of POx nanorods as a next generation stealth drug delivery platform.

Abstract
The use of crystallization as a tool to control the self-assembly of polymeric and molecular amphiphiles in solution is attracting growing attention for the creation of non-spherical nanoparticles and more complex, hierarchical assemblies. In particular, the seeded growth method termed living crystallization-driven self-assembly (CDSA) has been established as an ambient temperature and potentially scalable platform for the preparation of low dispersity samples of core-shell fiber-like or platelet micellar nanoparticles. Significantly, this method permits predictable control of size, and access to branched and segmented structures where functionality is spatially-defined. Living CDSA operates under kinetic control and shows many analogies with living chain-growth polymerizations of molecular organic monomers that afford well-defined covalent polymers of controlled length except that it covers a much longer length scale (ca. 20 nm to 10 μm). The method has been applied to a rapidly expanding range of crystallizable polymeric amphiphiles, which includes block copolymers and charge-capped homopolymers, to form assemblies with crystalline cores and solvated coronas. Living CDSA seeded growth methods have also been transposed to a wide variety of π-stacking and hydrogen-bonding molecular species that form supramolecular polymers in processes termed "living supramolecular polymerizations". In this article we outline the main features of the living CDSA method and then survey the promising emerging applications for the resulting nanoparticles in fields such as nanomedicine, colloid stabilization, catalysis, optoelectronics, information storage, and surface functionalization.

Abstract
Despite many advanced growth methodologies for organic nanofibers (ONFs), the lack of efficient and scalable ONF-based film preparation technologies has long been a hindrance in their practical application in organic electronic devices. Here, a typical cathode electrophoretic deposition (C-EPD) technology was developed to controllably produce ONFs and their corresponding thin films. Using the solvent effect and an external electric field force during the C-EPD process, a one-dimensional ONF network was formed, which exhibits compact molecular packing and superior optoelectronic properties in the thin-film state. Prototype sandwich-structure memory devices based on these ONF films exhibited a binary nonvolatile memory performance significantly superior than that of the bulk materials. This study provides an efficient and scalable ONF fabrication technology for high-performance electronic devices in various potential applications.
