Writing in the Journal of the American Chemical Society, scientists report the controlled exfoliation of layered metal organic frameworks (MOF).
MOF, compounds which consist of metal ions have been attracting increasing interest due to their attractive properties and in particular their high surface area.
Recently, 2-D MOF have emerged as an attractive class of 2D nanomaterials for molecular sieving, sensing and catalysis. However, synthesising 2D MOF has been problematic.
Here the authors report the the exfoliation of intrinsically layered MOF in a two-step process. First, intercalation with 4,4′-dipyridyl disulfide and second by exfoliating in trimethylphosphine. The technique allows for the creation of MOF with average thickness of 1nm with high yield.
