Exploration of new π-conjugated building blocks for construction of supramolecular polymers is at the forefront of self-assembly. Herein, we incorporate a highly planar anthanthrene skeleton into the design of two supramolecular monomers 1 and 2. Their supramolecular polymerization have been comprehensively investigated by spectroscopic studies.

Fabricating organic semiconducting materials into large-scale, well-organized architectures is critical for building high-performance molecular electronics. While graphene nanoribbons (GNRs) hold enormous promise for various device applications, their assembly into a well-structured monolayer or multilayer architecture poses a substantial challenge. Here, we report the preparation of length-defined monodisperse GNRs via the integrated iterative binomial synthesis (IIBS) strategy and their self-assembly into submicrometer architectures with long-range order, uniform orientation, as well as regular layers.

Enzyme-instructed signal generation at liquid-liquid interfaces presents a novel strategy for controlling and detecting biochemical processes on macroscopic scales. Here, we explore the self-assembly and jamming of pillar[5]arene (P[5]A) derivatives at the oil-water interface via a copper-mediated "click" reaction, providing a versatile platform for generating observable signals. The formation of a pillar[5]arenes network at the droplet interface reduces interfacial tension, allowing droplets to adopt various nonequilibrium shapes based on the interfacial jamming process.

The combination of chemotherapy and gene therapy holds promise in treating cancer. A key strategy is to use small interfering RNAs (siRNAs) to silence programmed death-ligand 1 (PD-L1) expression in cancer cells, disrupting tumor immune evasion and enhancing anticancer treatments, particularly when used in conjunction with chemotherapy drugs such as doxorubicin (Dox). However, effective codelivery of drugs and genes requires carefully designed carriers and complex synthesis procedures.

Combining polysaccharides with polypeptides enables growth of diverse nanostructures with minimal toxicity, low immune response, and potential biodegradability. However, examples of nanostructures combining polysaccharides with polypeptides are limited due to synthetic difficulties and related issues of solubility, purification, and characterization, with previous reports of polysaccharide-block-polypeptide block copolymers requiring methods such as polymer-polymer coupling and post-polymerization modifications paired with difficult purification steps. Here, we synthesized dextran-block-poly(benzyl glutamate) block copolymers in water via polymerization-induced self-assembly (PISA) to form nanostructures in situ, studying their morphologies using experimental methods and molecular modeling.
