The themes of coordination-driven self-assembly, host–guest interactions, and supramolecular polymerization are unified in an orthogonal noninterfering fashion to deliver side-chain poly[2]­pseudorotaxanes. Specifically, a bis­(p-phenylene)-34-crown-10 derivative 1 bearing two pyridyl groups polymerizes into a side-chain poly[2]­pseudorotaxane upon the addition of di-Pt­(II) acceptor 4 in the presence of paraquat. Interestingly, by adding a competitive guest 3, the poly[2]­pseudorotaxane can realize a conversion in one pot.
