Threading the needle: guest transport in a versatile 0D porous molecular crystal

Porous host crystals of the metallocycle [Cu₂(1,3-bis(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene)₂Cl₄]·2CH₃OH are permeable to a series of small organic guests despite their lack of permanent channels.

Single-crystal to single-crystal guest exchange and phase transformations in a porous metallocycle

The acetonitrile guest molecules in this porous metallocycle can be exchanged for different solvent molecules in a single-crystal to single-crystal manner. These guest exchanges are accompanied by a phase transformation in the solid state.

The Fields of Crystal Engineering and Ionic Liquids Are Actually Quite Similar

The fields of Crystal Engineering, the study and engineering of the crystalline solid state of materials, and Ionic Liquids, the study and engineering of the liquid state of salts that typically melt below 100, would seem at first glance polar opposites, but are they?
