제목 Reversible transformation of peptide-mimic poly(n-hexyl isocyanate) in thin films via selective solvent-annealing
초록 For the first time, We demonstrate the conformational and structural details of peptide-mimic poly(n-hexyl isocyanate) (PHIC), which have received considerable attention because of their unique characteristics, structural feature and potential applications in various fields. A well-ordered hexagonal close packing (HCP) structure of PHIC with 83 helical conformation was unequivocally observed in the nanoscale thin films that were selectively annealed with carbon disulfide (CS2). In another case, a well-ordered multi-bilayer structure of the polymer with β-sheet conformation was also unequivocally formed in the films that were selectively annealed with toluene. In addition, reversible transformation between these two self-assembled structures was demonstrated by consecutive annealings with CS2 and toluene.
