摘要

The design and synthesis of a Lonsdaleite (Ion) network is an attractive and challenging supramolecular target. Our reticular synthesis strategy of slow diffusion of solutions of a simple rigid tetrahedral ligand and a Ag(I) metal ion, at room temperature and atmospheric pressure, resulted in both Ion-MOFs and diamondoid (dia-MOFs) and associated 2D honeycomb networks. Solvent appeared to play a key role in templating the formation of these related networks. Nano indentation studies show that a dia-MOF was 42% harder than a lon-MOF counterpart. The lon-MOFs were thermally stable and retained integrity until 370 degrees C while dia-MOFs exhibited stepwise collapse after initial loss of solvents. As ion networks are often only qualitatively identified, Cremer-Pople ring puckering analysis was used to quantify the degree of distortion in the lon and related 4-connected 6(6) networks.
