title: Tailor-made metal-organic frameworks from functionalized molecular building blocks and length-adjustable organic linkers by stepwise synthesis.
abstract: In this work, we have demonstrated a family of diamondoid metal-organic frameworks (MOFs) based on functionalized molecular building blocks and length-adjustable organic linkers by using a stepwise synthesis strategy. We have successfully achieved not only "design" and "control" to synthesize MOFs, but also the functionalization of both secondary building units (SBUs) and organic linkers in the same MOF for the first time. Furthermore, the results of N(2)  and H(2)  adsorption show that their surface areas and hydrogen uptake capacities are determined by the most optimal combination of functional groups from SBUs and organic linkers, interpenetration, and free volume in this system. A member of this series, DMOF-6 exhibits the highest surface area and H(2)  adsorption capacity among this family of MOFs.
