Crystal Engineering

Coordination-based polymers and metal-organic frameworks (MOFs) have been explored since their discovery at the beginning of the 18th century. Such materials are generated by the dozens in a gold-rush-type search for properties mainly related to the storage and release of energy (e.g., hydrocarbons, dihydrogen). How the molecular components, metal salts and experimental conditions control the dimensions, shapes, chirality and homogeneity of these materials is barely known. Using achiral ligands that binds late-transition metals in a defined manner, we address issues related to the mechanism underlying the formation of unusual and chiral structures. For two overviews of our recent work, see the Weizmann Wonder Wander pages about Yo-Yo crystals and the formation of hollow structures or watch it on YouTube.
