Citação: Teixeira, F. C.; Rangel, C. M. Synthesis of azole biophospanates presursors for proton-exchange membrane for application in high temperature PEM fuel cells. In: 4th International Seminar on Advances in Hydrogen Energy Technologies : Oportunities and Challenges in a Hydrogen Economy, Viana do Castelo, Novembro 10-11, 2011, 5 p.
Resumo: This work reports the synthesis and characterization of phosphonate-, hydroxybisphosphonate- and aminobisphosphonatebenzimidazole derivatives substituted at N-1 position and new regioisomers phosphonateand aminobisphosphonatebenzotriazole derivatives substituted at N-1 or N-2 positions. The compounds were characterized by NMR, IR spectroscopy and mass spectrometry (low and high resolution) allowing the assignment of their structure, including the identification of regioisomers. These azoles will be precursors of mesoporous silica host to produce novel membranes materials with high proton conductivity for intermediate temperature PEMFCs.
