MOFs get attraction: Supraparticle self-assembly of a colloidal metal–organic framework (MOF) is achieved through simple capillary and van der Waals attractions. When suspensions of MOF particles are allowed to evaporate, hexagonal packings with controlled crystal orientation result (see scheme). The self-assembly can be visualized at the single-particle level.
