1,1,1,3,3,3-Hexafluoro-2-propanol (HFIP) as a novel and effective solvent to facilely prepare cyclodextrin-assembled materials

We found that cyclodextrins (CDs) have a high solubility in 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP). Evaporating HFIP from CD solutions on a glass plate gave crystalline solids composed of channel-type CD assemblies, and electrospinning with an HFIP solution of CDs fabricated CD microfibers.
