Reversible Contraction/Expansion Behavior by Thermally Adaptive Deformation
(A) Schematic representation of the thermal deformation of the supramolecular assemblies between 2D film and hyper-branched network.
(B) TEM images of the supramolecular assemblies at 0°C. Inset image shows the pores with nanometer diameter.
(C) TEM images of the supramolecular assemblies at 40°C. Inset image shows the “extended” pores with larger diameter.
(D) AFM images and section height analysis of the 2D supramolecular assemblies at 40°C.
(E) Normalized frequency distribution of the pore diameter of the 2D assemblies at 0°C and 40°C. The statistical data were collected from 200 randomly selected pores in TEM images.
(F) DLS results of the supramolecular polymers trans-1@CB[8] solution (1 mM, H2O) at varied temperature.
