A synergistically directed assembly approach to distinctive metal-organic frameworks utilizing both donor-acceptor (D-A) interaction from aromatic systems and coordination interactions is presented. Based on such an approach, the coronene-tpt (tpt = 2,4,6-tri(4-pyridyl)-1,3,5-triazine) stacks based coronene-MOF-1-4 have been successfully fabricated. Their structural discrepancies with coronene- absent control products, 1 '-4 ', illustrate clearly the significance of coronene-tpt based D-A interactions in these architectures. All these coronene-MOFs contain varied coronene-tpt stacks as organic secondary building blocks (SBUs), which are closely interrelated with the coordination based framework structures. Moreover, porous coronene-MOF-1 and -2 exhibit high physicochemical stability and significant light hydrocarbons storage and separation performances.
