Optimization of Anti-kinking Designs for Vascular Grafts Based on Supramolecular Materials

Frontiers in Materials, 2020
Synthetic vascular grafts to be applied as access grafts for hemodialysis often require anti-kinking properties. Previously, electrospun microporous vascular implants based on synthetic supramolecular materials have been shown to perform adequately as ...

The synthesis of 2-pyrimidinone nucleosides and their incorporation into oligodeoxynucleotides

Nucleic Acids Research, 1989
The synthesis of 1-(beta-D-2'-deoxyribosyl)-2-pyrimidinone (dK) and its 5-methyl derivative (d5) from 2'-deoxycytidine or 2'-deoxythymidine, respectively, via silver oxide oxidation of 4-hydrazinopyrimidines is described. The necessary hydrazine substituted pyrimidine nucleosides have been prepared by transamination of a protected cytidine derivative ...

Bio‐Orthogonally Crosslinked Supramolecular Polymer Bottlebrush Hydrogels for Long‐Term 3D Cell Culture

Advanced Functional Materials, Volume 36, Issue 40, 18 May 2026.
Fibrous benzenetrispeptide (BTP) hydrogels, fabricated via strain‐promoted azide‐alkyne cycloaddition (SPAAC) crosslinking, form robust, bioinert networks. These hydrogels can support 3D cell culture, where cell viability and colony growth depend on the fiber content.

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

Advanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Carbon Dot Self‐Assembly: Bottom‐Up Fabrication, Morphological Evolution, Luminescence Regulation, and Advanced Applications

Aggregate, Volume 7, Issue 5, May 2026.
The self‐assembly of carbon dots, which enables precise control over their macroscopic architectures and collective properties, profoundly enhances their functionality. This review systematically summarizes the field through four key aspects—morphology control, luminescence modulation, assembly mechanisms, and advanced applications—and thereby offers a

Uniqueness of Supramolecular Systems

Macromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.
Thanks to the variety of classes of supramolecular systems, they have been widely used in various applications. For example, in sensing devices, catalysis, and biomedicine. An example of a conventional photovoltaic material converted into electrical energy. Selective UV or NIR absorbers are required to produce materials with low or no coloration.
