Polar Thin Films Produced by Phosphonium Liquid Crystals: Two-Dimensional Self-Assembled Ionic Layers with Spontaneous Polarization

Abstract

This work was supported by the Robert A. Welch Foundation. We thank Prof. Zoltan Schelly for assistance and discussions in obtaining the electric birefringence data, Prof. Kurt Mislow for helpful discussions on stereochemistry, and Prof. Barton Kaman for use of the mass spectrometry equipment. The authors would also like to thank the North Carolina Supercomputing Center for their partial support of the computational component of this work.

Novel anhydrous organic proton conductors for fuel cells

“…The assembled structures are directed by the choice of phase so that structurally controlled materials could be prepared by quenching from the appropriate fluid phase to the solid state. 6,7 LCs are among the most promising compounds for applications in proton-conducting materials.…”
