A family of 17 sugar-based alternating copolymers was synthesized via photoinduced radical copolymerization of naturally occurring levoglucosenone (LGO) and commercially available vinyl ethers. The r...

We report a highly selective CMP of dicycloalkenes using G2 catalysts, obtaining well-defined polymer structures with excellent cascade efficiency (>99%) and TON up to 3550. Sulfonamide-linked dicycl...

Transition metal hydrides (TMHs) find numerous applications across fields from catalysis to H2 storage. Yet, determining the structure of TMHs can remain a challenge, as hydrogen is difficult to detec...

Designing molecular crystals for practical applications requires precise control over intermolecular interactions. We report a click-to-stack strategy to enable facile construction and systematic structural modification of tetraarene-fused cyclooctatetraenes. These saddle-shaped molecules self-assemble into one-dimensional columns with exceptional precision, driven solely by weak van der Waals interactions. Single-crystal X-ray crystallographic and computational studies revealed fully eclipsed π–π stacking, reinforced by the shape complementarity of the negatively curved molecular contour. With alkoxy groups tethered, the antiparallel alignment of coaxial cable-like assemblies produces centimeter-long voidless crystals that exhibit remarkable structural durability under mechanical stress. These glow stick-like elastic crystalline rods display optical waveguiding properties, demonstrating the practical utility of highly anisotropic molecular assemblies with structural uniformity and resilience.

In recent years, pollution from plastic waste has intensified the demand for sustainable polymers. Hence, biomass-derived degradable polymers offer a promising solution. For example, levoglucosenone, ...

Donor–acceptor alternating conjugated polymers (D–A CPs) are one of the best materials for high-performance organic electronic devices, owing to their low bandgap and high charge carrier mobility. How...

Here, we present an efficient synthetic route to biobased alternating copolymers via the living radical copolymerization of naturally occurring levoglucosenone (LGO) and dienes. By employing reversible addition–fragmentation chain transfer (RAFT) polymerization, well-defined LGO-derived copolymers were readily synthesized featuring high degrees of alternation, well-controlled molecular weights, and excellent end-group fidelity. Additionally, the alternating copolymers exhibited thermal and mechanical properties comparable to those of the commodity polystyrene. Furthermore, an on-demand metathesis degradation was identified, highlighting their potential as degradable materials.

We synthesized linear/cyclic poly(allenamer)s (PAs) from cycloallenes by CAAC-Ru catalysts. Mechanism studies suggested CAAC ligands enhanced the stability of propagating Ru vinylidene, producing var...

Ring expansion metathesis polymerization (REMP) has emerged as a potent strategy for obtaining cyclic polymers over the past two decades. The scope of monomers, however, remains limited due to the poo...
