The invention relates to single crystals of metal-organic framework materials comprising at least one aluminium metal ion, processes for preparing the same, methods for employing the same, and the use thereof. The invention also relates to monocrystalline or polycrystalline aluminium metal-organic frameworks.
Branching out: Condensationpolymerization of AB2 monomer proceeds selectively from a core molecule owing to the change of substituenteffects between the monomer and the polymer (see scheme). Hyperbranchedpolyamides are obtained with very low polydispersity and controlled molecular weight determined by the monomer/core feed ratio.
