| Abstract |
Metal-organic frameworks (MOFs) are organic-inorganic hybrid materials consisting of metal clusters (or ions) and multitopic organic ligands. MOFs generally have three-dimensional frameworks with permanent porosity, and sometimes they show flexible frameworks. The flexibility of MOFs (i.e., structural changes of MOF frameworks) is changed by external stimuli such as pressure, guest molecular contact, solvent, etc. Recently, we have revealed that the position of functional groups and electronic density of ligands are also directly related with the flexibility changes of MOFs. Among the various combinations of functionalities, only NH2-Cl, NH2-Br, NH2-OMe, OMe-OMe displayed the flexibility changes by the position of functional groups (i.e., regioisomeric of functional group).1-3
Herein, we have expanded our regioisomerism research to metal effect on MOFs. Using para- and ortho- NH2-Cl functionalized ligands, we have successfully prepared three MOFs with different metal salts (cobalt, copper, and zinc) but with identical structures. Their structural analysis along with gas adsorption changes will be discussed in this presentation.
