Thin films of HKUST-1 fabricated by dip coating using nanoparticle suspension (sol) of G⊃MEH: a) on a glass substrate, b) thin film demonstrating reversible color change upon heating, c) AFM height topography, d) surface roughness profile extracted from AFM line scan marked in (c). e) Young's modulus stiffness map of the thin film surface measured by AM–FM technique. The wide range of elastic moduli obtained (3–6 GPa) may be linked to elastic anisotropy,[36] suggesting that the external facets of HKUST-1 nanocrystals are oriented across a range of crystallographic directions.
