Combining the unique corona structure of worm‐like patchy micelles immobilized on a polymer fiber with the molecular self‐assembly of 1,3,5‐benzenetricarboxamides (BTAs) leads to hierarchical superstructures with a fir‐tree‐like morphology. For this purpose, worm‐like patchy micelles bearing pendant, functional tertiary amino groups in one of the corona patches were prepared by crystallization‐driven self‐assembly and immobilized on a supporting polystyrene fiber by coaxial electrospinning. The obtained patchy fibers were then immersed in an aqueous solution of a tertiary amino‐functionalized BTA to induce patch‐mediated molecular self‐assembly to well‐defined fir‐tree‐like superstructures upon solvent evaporation. Interestingly, defined superstructures are obtained only if the pendant functional groups in the surface patches match with the peripheral substituents of the BTA, which is attributed to a local increase in BTA concentration at the polymer fibers’ surface.

Die Kombination der Patch‐artigen Koronastruktur von oberflächenkompartimentierten Zylindermizellen mit der molekularen Selbstassemblierung von 1,3,5‐Benzoltricarboxamiden (BTAs) ermöglicht die Herstellung hierarchischer Überstrukturen mit Tannenzweig‐artiger Morphologie. Hierfür wurden Patch‐artige Zylindermizellen, die funktionelle tertiäre Aminogruppen in einem der Korona‐Patches aufweisen, mittels kristallisationsinduzierter Selbstassemblierung hergestellt und durch koaxiales Elektrospinnen auf einer Polystyrol‐Trägerfaser immobilisiert. Die erhaltenen Patch‐artigen Fasern wurden in eine wässrige Lösung eines mit tertiären Aminogruppen funktionalisierten BTA getaucht, um die Selbstassemblierung zu definierten Tannenzweig‐artigen Überstrukturen nach Verdampfen des Lösungsmittels zu induzieren. Definierte Überstrukturen werden nur erhalten, wenn die funktionellen tertiären Aminogruppen in den Oberflächenkompartimenten mit den peripheren Substituenten des BTA übereinstimmen. Dies wird auf eine lokale Erhöhung der BTA‐Konzentration an der Oberfläche der Patch‐artigen Polymerfasern zurückgeführt.

“…However, the modular design of the patchy hybrid nonwovens enables a facile adaption to the needs of different catalysis systems—for example, by an exchange of the support material or by varying the type of NPs. Moreover, it is possible to render the functionalized patches thermo-responsive [ 194 ], which opens access to catalytic reactions regulated by an inherent temperature control.…”

Crystallization-driven self-assembly (CDSA) of block copolymers bearing one crystallizable block has emerged to be a powerful and highly relevant method for the production of one- and two-dimensional micellar assemblies with controlled length, shape, and corona chemistries. This gives access to a multitude of potential applications, from hierarchical self-assembly to complex superstructures, catalysis, sensing, nanomedicine, nanoelectronics, and surface functionalization. Related to these applications, patchy crystalline-core micelles, with their unique, nanometer-sized, alternating corona segmentation, are highly interesting, as this feature provides striking advantages concerning interfacial activity, functionalization, and confinement effects. Hence, this review aims to provide an overview of the current state of the art with respect to self-assembly concepts, properties, and applications of patchy micelles with crystalline cores formed by CDSA. We have also included a more general discussion on the CDSA process and highlight block-type co-micelles as a special type of patchy micelle, due to similarities of the corona structure if the size of the blocks is well below 100 nm.
