Title: macromolecular rotaxane Long Title: IUPAC Gold Book - macromolecular rotaxane DOI: 10.1351/goldbook.13968 Status: current Definition Rotaxane, at least one component of which is a macromolecule. Notes 1) A macromolecular rotaxane is composed of a macromolecular chain with either at least one cyclic molecule threaded onto its linear section or at least one linear molecule threaded through its threadable cycle. 2) Rotaxane constitutional unit(s) may be located within a specific part of a macromolecular rotaxane: (i) within end-group(s); (ii) within a main chain (see main-chain macromolecular rotaxane); (iii) within side chains (see side-chain macromolecular rotaxane).
