As we enter the age of artificial intelligence (AI), new technologies will be needed to
“sample” environmental conditions to provide data to AI systems that will yield a specific …

Cyclic polymers present a topology that differ significantly from their linear counterparts due
to their circular structure and therefore, the lack of chain ends. These simple characteristics …

Here we demonstrate the synthesis of cyclic polyacetylene (c-PA), or [∞] annulene, via
homogeneous tungsten-catalysed polymerization of acetylene. Unique to the cyclic structure …

Described here is a direct entry to two examples of 3d transition metal catalysts that are
active for the cyclic polymerization of phenylacetylene, namely,[(BDI) M {κ2‐C, C …

Ring-expansion metathesis polymerization (REMP) has shown potential as an efficient
strategy to access cyclic macromolecules. Current approaches that utilize cyclic olefin …

The synthesis of well-defined cyclic polymers is crucial to exploring applications spanning
engineering, energy, and biomedicine. These materials lack chain-ends and are therefore …

Presented is the synthesis of cyclic polyacetylenes from alkynes and a study probing the
functional group tolerance of catalyst 1. The synthesized polymers were characterized by …

This report describes an approach for preparing tethered tungsten-imido alkylidene
complexes featuring a tetra-anionic pincer ligand. Treating the tungsten alkylidyne [t …

Polymer-topology effects can alter technologically relevant properties when cyclic
