Reproduced with permission.168 f) Reaction scheme of aryl diazonium functionalization of BP. AFM images of BP before and after ambient exposure. g) A BP flake immediately after 30 min functionalization in 4‐NBD solution. h) The same flake in panel (b) after 10 d of exposure to ambient conditions. Scale bars are 2 µm. Reproduced with permission.170 Copyright 2016, Macmillan Publishers Limited. i) AFM images of BP prepared by solvent exfoliation in NMP. The leftmost image presents the entire flake, and the images progressing to the right present magnified views immediately after exfoliation up to 7 d in ambient conditions. The arrows indicate the same position on the BP flake, and all scale bars are 1 µm. Reproduced with permission.106 Copyright 2015, American Chemical Society.
