Amine assisted top-down delamination of the two-dimensional metal–organic framework Cu₂(bdc)₂

Abstract

(bdc - 1,4-benzenedicarboxylate), two different strategies of amine assisted delamination turned out to be successful to obtain nanoplates. Particles with thicknesses of around 70 nm were obtained by direct delamination of crystals using octylamine. The surfactant (polyvinylpyrrolidone) assisted synthesis combined with a post-synthetic amine delamination step enabled a further reduction of the thickness of the MOF nanoplates down to 4-14 nm.
