Abstract (Summary)

A new strategy for creating homochiral metal-organic frameworks is demonstrated, through fusion of pillaring and templating concepts. This strategy makes use of the synergy among various chemical interactions during self-assembly process, and leads to the synthesis of a series of homochiral frameworks. In the presence of only pillar-to-pillar π-π interactions, inter-pillar forces compete again metal-pillar interactions, resulting in mismatch between pillar-to-pillar and metal-to-metal separations and consequently 2-D materials without pillaring. To create 3-D materials, a method is developed to use various aromatic molecules, polycyclic aromatic hydrocarbons in particular, as templates to modulate the inter-pillar interaction and separation, leading to the formation of 3-D homochiral frameworks. The use of aromatic molecules, especially hydrocarbons, as structure-directing agents, represents a new approach in the development of crystalline porous materials. Aromatic templates can be post-synthetically extracted to yield flexible porous homochiral materials with gate-opening gas sorption behaviors for both N2 and CO2 at partial pressures tunable by temperatures.
