Abstract
Methods of synthesizing crystalline metal-organic frameworks (MOFs) comprising polytopic organic linkers and cations, where each linker is connected to two or more cations, are provided. In the disclosed methods, the linkers are reacted with a compound of formula MX, where M is cationic Be, Mg, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Zr, Nb, Mo, Ru, Rh, Pd, Cd, or Hf, X is anionic, n and m are integers. The reacting is buffered by a buffer devoid of metal coordinating functionality when the pKa of the anion is below a threshold related to the lowest pKa of the linker. The reacting is optionally not buffered when the pKa of the anion is at or above this threshold. The disclosed methods lead to product phase MOF in which crystal growth is controlled leading to control over molecular diffusion.
