Three-dimensional fivefold interpenetrating microporous metal–organic framework based on mixed flexible ligands

The chiral diamondoidlike Cd(II) containing coordination polymer {[Cd(oba)(bib)]·2H2O}n (1) (oba = 4,4′-oxybis(benzoate), bib = 1,4-bis(2-methyl-imidazol-1-yl)butane) is reported; the 3D networks interpenetrate fivefold, nevertheless leave cavities capable of including sizable guest molecules. This compound also exhibits high thermal stability and blue-shift emission, and can be explored for potential blue luminescent materials.

An novel diamondoidlike coordination polymer {[Cd(oba)(bib)]·2H2O}n (1) have been synthesized. Interestingly, the compound still exhibits significant void space that may be filled with guest H2O molecules in spite of the fivefold interpenetration that occurs in the solid. Besides, this compound also exhibits high thermal stability and blue-shift emission, and can be explored for potential blue luminescent materials.Figure optionsDownload as PowerPoint slide
