Erratum: Strong and flaw-insensitive two-dimensional covalent organic frameworks (Matter (2021) 4(3) (1017–1028), (S2590238521000011), (10.1016/j.matt.2021.01.001))

(Matter 4, 1017–1028; March 3, 2021) The authors regret that the printed version of above article contained two errors. The correct and final version are as follows. These do not affect the results, findings and conclusions. 1. Table S1 in supplementary document The first correction is that the value of fracture strength, Young's modulus and fracture toughness of COF films in Table S1, the correct value should be 0.75 ± 0.34 GPa, 10.38 ± 3.42 GPa and 0.55 ± 0.09 MPa√m, respectively. 2.
