Research is being done to find a material to improve the efficiency of the ethanol fuel cell by using a platinum free catalyst. Mo2WO2(O2CCH3)6 cluster was synthesized using Mo2(O2CCH3)4 dimer and Na2WO4. One ionic liquid, EMImBF4, was synthesized using methylimidazolim and chloroethane in the first step, and EMImCl and NaBF4 in the second step. The electrochemical properties of the ionic liquid and the metal cluster were studied. A potential window for the EMImBF4 was found to be 3.2 V. The ionic liquid has a wider potential window, and allowed for the observation of the redox properties of Mo2WO2(O2CCH3)6. The electrochemistry …

The synthesis of poly(arylene ether sulfone)s, with a pendant aryl iodide, was achieved via nucleophilic aromatic substitution (NAS) polycondensation of 3-iodo-3',5'-difluoro-diphenylsulfone (2) with Bisphenol-A. Monomer 2 was prepared by the reaction of 3, 5-difluorodiphenylsulfone with N-iodosuccinimide (NIS). Model reactions indicated that the iodo group was stable to NAS conditions. Both GC/MS analysis and NMR spectroscopy indicated quantitative displacement of the two fluorine atoms while the iodo group remained untouched. Furthermore, the modification of the iodo polymer was achieved via Suzuki-Miyaura cross-coupling reaction with phenyl, naphthyl, and phenylacetyl boronic acids. The thermal properties of the polymers were evaluated via DSC and …
