From: Elastic films of single-crystal two-dimensional covalent organic frameworks
a, Force-displacement curves of 20 cycles of loading (upper) and unloading of AFM tips with a radius of ~ 100 nm at the same position under constant rate. b, Rupture force-displacement curves of 2DCOF-2 film at the same indentation position as in (a).
