| Abstract: | The development of precise folding techniques for synthetic polymer chains that replicate the unique structures and functions of biopolymers has long been a key challenge. In particular,spiro-type (i.e., 8-, trefoil-, and quatrefoil-shaped) polymer topologies remain challenging due to their inherent structural complexity. Herein, we establish a folding strategy to producespiro-type multicyclic polymers via intramolecular ring-opening metathesis oligomerization of the norbornenyl groups attached at predetermined positions along a synthetic polymer precursor. This strategy provides easy access to the desiredspiro-type topological polymers with a controllable number of ring units and molecular weight while retaining narrow dispersity (& x189; < 1.1). This effective strategy marks an advancement in the development of functionalized materials composed of specific three-dimensional nanostructures. Intramolecular ring-opening metathesis oligomerisation is a useful method for constructing multicyclic polymer cages. Here, it is applied to the synthesis of spirocyclic polymers with figure-8, trefoil, and quatrefoil structures with low polydispersity. |
