A new class of sulfur‐free, oxygen‐bridged dibenzofuran‐based polymers is developed for ultrahigh‐refractive‐index applications. The rigid π‐extended architecture and enhanced molecular polarizability enable exceptional optical performance, combining refractive indices up to 1.848 with high Abbe numbers and full visible transparency. This work offers a

Mono‐Material Polydisulfides for Pressure Sensitive Adhesive Tapes With Closed‐Loop Recyclability
A high‐performance pressure‐sensitive adhesive (PSA) tape is developed where both the adhesive layer and plastic backing layer can be recycled back to monomer in a closed‐loop cycle. Both layers of the tape are composed of analogous polydisulfide copolymers using only two unique monomers, thus giving it a mono‐material design and enabling recycling of ...

Preferential Interfacial Engineering of Hydrogels via Interdigitated Nanoparticle Assembly
Robust surface functionalization of hydrogel surfaces is performed via interdigitated metal nanoparticle assembly, inducing strong affinity with the hydrogel matrix. The partially exposed nanoparticle domains act as interfacial nanobridges that mediate both chemical and physical bonding with diverse materials, including small molecules, fluorous ...
