Made in Water: A Stable Microporous Cu(I)-carboxylate Framework (CityU-7) for CO2, Water, and Iodine Uptake
摘要:
Using water as the sole solvent, the bifunctional molecule tetrakis(methylthio)-1,4-benzenedi-carboxylic acid (TMBD) was reacted with Cu(CH3CN)(4)BF4 to form a robust microporous metal-organic framework (MOF, CityU-7) featuring Cu(I) ions being simultaneously bonded to the carboxyl and thioether donors. The MOF solid is stable in air and can be easily activated by heating, without the need for treatment with organic solvents. The subnanoscopic pores (ca. 0.6 nm) of the host net allow for uptake of CO2 and H2O but exhibit lesser sorption for N-2 at 77 K. The microporous net can also be penetrated by I-2 molecules.

A silver(I) sulfide species is now imbedded in a porouscoordinationnetwork. Such a composite system builds on the molecule tetrakis(methylthio)-1,4-benzenedicarboxate that holds out the hard carboxylate to europium(III) to form a host net, while taking on AgCl using its soft sulfur side arms. AgCl is then treated with H2S to form the dark-colored Ag2S species, while leaving the hard host net intact
