Long‐Term Hydrophilic, Anti‐Clotting, and Anti‐Fibrotic Dynamic Covalent Silicone‐Based Biomaterials

Advanced Healthcare Materials, Volume 15, Issue 24, 25 June 2026.
Dynamic covalent crosslinking of a Schiff‐base silicone elastomer with hydrazide‐functionalized polymers is demonstrated to improve the long‐term hydrophilicity as well as the anti‐fouling and anti‐clotting properties of PDMS implants. The hydrazone‐functionalized material prevents hydrophobic recovery, resists clotting, and significantly reduces ...

Dynamic Supramolecular Polyurethane Elastomers Enabling Bioinspired Strain‐Adaptive Stiffening to Resolve the Softness–Strength Paradox

Advanced Science, Volume 13, Issue 31, 4 June 2026.
Segmental‐level molecular engineering of a supramolecular polyurethane elastomer integrates strain‐adaptive chains, soft elastic segments, and dynamic hydrogen bonding motifs. This design reconciles skin‐like softness with muscle‐level strength, offering a sustainable and high‐performance material platform for next‐generation artificial skin and soft ...

Dihydroquinazolinones by Titanocene‐Catalyzed Reductive Radical Addition to Quinazolinones

Chemistry – A European Journal, Volume 32, Issue 21, 1 June 2026.
Tri‐ and tetracyclic dihydroquinazolinones or quinazolinones by titanocene catalysis: A highly diastereoselective and efficient reductive radical addition to quinazolinones enables an unprecedented entry to pharmaceutically relevant dihydroquinazolinones by avoiding the interception of radical intermediates prior to the slow radical addition.

Thiazolidinedione–Pyrazolopyrimidinone Molecular Hybrids With Alkyl Spacers: Potential Antitubercular Agents Complemented by Molecular Modeling

ChemistrySelect, Volume 11, Issue 24, 25 June 2026.
We report the synthesis of 21 novel thiazolidinedione–pyrazolopyrimidinone derivatives (12a–u), prepared by coupling thiazolidinedione and pyrazolopyrimidinone pharmacophores through various alkyl linkers. The compounds were characterized spectroscopically and evaluated against the Mtb H37Rv strain, identifying compounds 5c and 5d as potent ...

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
