Solvent-assisted linker exchange (SALE) was performed on a pillared-paddlewheel metal-organic framework (MOF), SALEM-5, to achieve incorporation of longer linkers into the material. The 9-Å meso-1,2-di(4-pyridyl)-1,2-ethanediol pillar of SALEM-5 was successfully replaced by 11-Å, 14-Å, and 17-Å pillars to generate daughter MOFs SALEM-6, SALEM-7, and SALEM-8. The daughter frameworks possess more open cages, as was demonstrated by structural modeling from the powder x-ray diffraction patterns, and larger solvent accessible space, as was demonstrated by TGA. Finally, a study was performed to examine the effect of pKa of monoprotonated dipyridyl pillars (as an indicator of the Zn-L bond strength) on the outcome of SALE. In the experiment, the researchers used many compounds, for example, 1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1Safety of 1,4-Diiodo-2,3,5,6-tetramethylbenzene).
1,4-Diiodo-2,3,5,6-tetramethylbenzene (cas: 3268-21-1) belongs to iodide derivatives. Organoiodine compounds occur widely in organic chemistry, but are relatively rare in nature. Polyiodoorganic compounds are sometimes employed as X-ray contrast agents, in fluoroscopy, a type of medical imaging. This application exploits the X-ray absorbing ability of the heavy iodine nucleus.Safety of 1,4-Diiodo-2,3,5,6-tetramethylbenzene
