Proton Transport in Self-Assembling Organic Compounds — •Manuel Schrader and Denis Andrienko — Max Planck Institute for Polymer Research, Ackermannweg 10, 55128 Mainz

Organic phosphonic acid derivatives are promising materials as proton-conducting electrolytes in water-free proton exchange membrane fuel cells. In this work atomistic molecular dynamics simulations of phosphonic-acid functionalized organic conjugated compounds have been carried out. In order to conduct simulations, force fields for these molecules have been developed with the aid of first-principle calculations. In the simulations supramolecular self-assembly in columnar structures and formation of hydrogen bond networks leading to proton transport could be observed.
