A Hydrogen Peroxide-Responsive Supramolecular Pseudopolyrotaxane Driven by Pillararene-Based Molecular Recognition and Metal-Ligand Interaction

Abstract

A hierarchical self-assembled linear supramolecular poly-pseudorotaxane was constructed by first forming a discrete, bifunctional pseudorotaxane monomer via the strong complexation between selenium-containing pillararene (SeP5) and ditopic guest (G), followed by a polymerization step through coordination with appropriate metal centers. This orthogonal strategy utilizes host-guest interactions to fabricate tunable building blocks, thereby generating linear supramolecular polymers with programmable structure and high uniformity.
