12. Experiments were done in a glovebox with dry and oxygen-free solvents and atmosphere. Typically, one uses 1 equiv of catalyst (NICOD) per dry complex (based on the monomer inside), 2 equiv of COD, and 3 equiv of PPh3. The polymerization takes around 24 h at 60°C. One adds then 1 equiv (compare to the monomer) of 9-bromo-anthracene and 1 equiv of catalyst (NICOD) and maintains a temperature of 60°C for 16 h.
13. Workup consists of successive centrifugation and precipitation in acetone and in water to remove non-water-soluble compounds. Yield is typically around 20%.

15. This sample was obtained by adding a small amount of NMP to a solution of polyrotaxane in DMSO to break down the aggregates.
