Experimental and computational details The synthesis and characterization of sulfonate substituted poly(diphenylene- vinylene) lithium salt (PDV.Li) and its cyclodextrin polyrotaxane derivative (PDV.Li⊂β-CD, with a threading ratio of 2 cyclodextrins per repeat unit) used in this work is described elsewhere 1 . All data shown were taken for PDV.Li and PDV.Li⊂β-CD solutions in water/propanol mixtures at a concentration of 5x10 -3 mg·mL -1 and 1.1x10 -2 mg·mL -1 respectively, in order to account for the different molecular weight and obtain the same optical density. Solutions were prepared from a "master" solution in water, i.e. 1 Electronic Supplementary Material (ESI) for Journal of Materials Chemistry C. This journal is © The Royal Society of Chemistry 2016
