TLDR
In this paper, a metal-organic framework was designed to bind aromatic guest molecules selectively, and the inclusions can be selectively readsorbed, even after the removal of included guest molecules, and they showed that the crystal lattice was thermally stable up to 350 °C.Abstract:
MICROPOROUS inorganic materials such as zeolites find widespread application in heterogeneous catalysis, adsorption and ion-exchange processes. The rigidity and stability of such frameworks allow for shape- and size-selective inclusion of organic molecules and ions1–4. Analogous microporous structures based on organic building blocks have the potential for more precise rational design, through control of the shape, size and functionalization of the pores5–8. Here we report the synthesis of a metal–organic framework designed to bind aromatic guest molecules selectively. The basic building block is a symmetric organic molecule, which binds metal ions9,10 to form layers of the metal–organic compound alternating with layers whose composition is determined by the functionalization of the starting molecules. The layers create channels in which guest aromatic molecules may be selectively bound. We show that the crystal lattice thus formed is thermally stable up to 350 °C, even after removal of included guest molecules, and that the inclusions can be selectively readsorbed.read more

Assembly of porphyrin building blocks into network structures with large channels
TL;DR: In this article, porphyrin building blocks are used to construct three-dimensional networks with the topology of the PtS structure, containing large channels, where the channels are filled with solvent molecules, and crystalline order is lost on solvent removal.
