Proton conductive cationic nanoporous polymers based on smectic liquid crystal hydrogen-bonded heterodimers

Abstract

The fabrication of a cationic nanoporous smectic liquid crystal network (LCN) based on hydrogen bonded heterodimers is presented.

Proton conductive ionic liquid crystalline poly(ethyleneimine) polymers functionalized with oxadiazole

“…Nonetheless, despite the fact that the conductivity values obtained for the hyperbranched ionic polymers are 3-4 orders of magnitude lower than those of obtained for non-mesogenic polymers (e.g. Naon, poly(ethylene oxide), or poly(sulfonic) polymers), 30,31 they are still high compared to other liquid crystalline materials, 10,11,32 providing an attractive strategy to prepare proton conductors.…”

Progress on highly proton-conductive polymer thin films with organized structure and molecularly oriented structure

“…Several groups have also recently reported proton conduction using an organized structure with thermotropic and lyotropic LC properties [104][105][106][107][108][109][110]. Ohno and co-workers reported anisotropic proton conduction by a self-assembled lyotropic columnar structure using phosphonium-type zwitterions and bis-(trifluoromethanesulfonyl)imide [111].…”

Recent synthetic advances in pyridine-based thermotropic mesogens

“…Hence, the p-p packing is minimized and nematic mesophase is induced despite the lengthening of the molecular axis. Mulder et al 53 prepared hydrogen bonded hetero-dimers for the fabrication of a cationic nanoporous smectic liquid crystal network (LCN). The preparation procedures depend on supramolecular aggregations composed of non-reactive benzoic acid rigid materials hydrogen bonded with a pyridyl-bearing reactive mesogen.…”
