Fig. 1: Macroscopic and microscopic changes in the dynamic MORFs in solid state by external stimuli and synthetic diagram of U-CB[8]-MPyVB.

a Macroscopic and microscopic changes in the dynamic MORFs in solid state by external stimuli (The figure on the left shows some movement on the micro level but with no changes on the macro level, the figure on the right shows the microstructure and macromorphology changes at the same time). b Synthetic diagram of U-CB[8]-MPyVB.
