A novel coordination polymer of zinc(II) biphenyldicarboxylate bearing a sulfone group, [Zn(sbdc)(H2O)3]·(H2sbdc)· H 2O (H2sbdc: sulfone biphenyldicarboxylic acid), has been synthesized. It is composed of a one-dimensional chain structure of alternating Zn(II) cations and sbdc anions. This coordination polymer possesses noncoordinating uncharged acid H2sbdc existing between the chains with hydrogen-bonding networks. The proton conductivity of [Zn(sbdc)(H 2O)3]· (H2sbdc) · H2O strongly depended on the relative humidity (RH), being 2.5 x 10-7 S cm-1 at 95% RH. The activation energy for proton conductivity was estimated to be 0.32 eV at 95% RH.

Triply fused 1,3-diazepine derivatives have been obtained by acidic reduction of rotationally locked and sterically hindered nitro groups in the presence of an aldehyde or ketone. The nitro groups are sited on adjacent rings of a dicyanodibenzothiophene-5,5-dioxide, which also displays fully reversible two-electron-accepting behavior. The synthesis, crystallographically determined molecular structures, and aspects of the electronic properties of these new molecules are presented.

A study was conducted to demonstrate significant sulfone-functionalized metal-organic frameworks (MOF) and gas sorption properties. The ligand (1,1'-biphenyl)-4,4'-dicarboxylic acid was functionalized with -SO3H groups and used as a linker to construct coordination polymers and conduct the investigations. The sulfone (-SO2) derivative of (1,1'-biphenyl)-4, 4'-dicarboxylic acid was isolated to conduct the investigations. The investigations revealed two novel three dimensional (3D) non-isoreticular porous MOFs with specific structures. The MOFs were isolated from controlled solvothermal reactions between (1,1'-biphenyl)-4,4'-dicarboxylic acid and Zn(NO3)2·6H2O. The unique structures of the MOFs were demonstrated as UoC-1 and UoC-2 that included the formation of novel inorganic secondary building units (SBUs) with significant double organic bridging connectivity in all directions.

A new sulfone functionalized vanadium metal-organic framework (MOF), denoted as SO2-COMOC-2, has been synthesized solvothermally. Its structural and gas sorption properties towards CO2 and CH4 have been evaluated and compared to those of the pristine COMOC-2 material. The SO2-COMOC-2 shows a remarkable increase in CO2 capacity at ambient pressure (2.13 mmol g-1 at 273 K vs. 1.23 mmol g-1 for the pristine COMOC-2). Additionally, the high pressure CO2 sorption isotherm shows a distinctive two-step sorption behavior with a final capacity of 12.45 mmol g-1 for SO2-COMOC-2 at 303 K, while for CH4 a typical Type I isotherm was obtained with a capacity of 4.13 mmol g-1. In situ synchrotron X-ray powder diffraction measurements have been carried out to characterize the structural flexibility of the materials, showing both the presence of large pore and narrow pore form. Furthermore, synchrotron XANES and a variety of spectroscopic techniques have been utilized to verify the presence of hydroxyl groups and the existence of the mixed vanadium oxidation states in the titled MOF structure.
