We recently reported the first two MOFs made from ellagic acid, including a bismuth ellagate (SU-101) and a zirconium ellagate (SU-102) both exhibiting high chemical stability and microporosity. Since then, crystal structures of a calcium ellagate and nickel ellagate have also been reported by other research groups as well as ellagate-based COFs . The original reported synthesis of SU-102, (DMA)2[Zr(EA)2], involved the use of a solvent mixture containing water, acetic acid and dimethylformamide (DMF). Of great importance to this work, DMF decomposes to form dimethylammonium (DMA) cations in the presence of water, which reside in the pores of the anionic SU-102 framework. Notably, DMF could be replaced as a reagent by other amines such as ammonia, dimethylamine, and diethylformamide, which in situ convert into ammonium, dimethylammonium, and diethylammonium cations respectively, all of which direct the formation of SU-102. The ammonium OSDAs can post-synthetically be exchanged for metal cations such as Li + , Na + , K + to tune the physical properties of the MOF such as accessible pore volume, surface area and selectivity in gas adsorption. However, these ammonium species used as OSDAs for SU-102 are all rather small OSDAs, comprising no more than five non-hydrogen atoms.
