“…[10] We expect that, if we can instill water molecules onto the entire surface of the IPMS without changing the Cub bi structures, they will provide an advanced electrolyte transporting proton via the macroscopically continuous hydrogen-bonding network of the water molecules.

“…44 One of the approaches for the induction of functional thermotropic Cub bi phases is the use of two-component assemblies. [51][52][53][54] For example, we achieved 3D proton transport in the Cub bi phases formed by the complexation of zwitterionic molecules and organic acids. 52,53 The acid dissociates in the presence of zwitterions, which enables the proton transport.…”

Title: Zwitterionic liquid crystals as 1D and 3D lithium ion transport media Zwitterionic liquid crystals forming nanosegregated columnar and bicontinuous cubic phases are used as media for the transport of lithium ions within the well-defi ned ionic nanochannels. Enhanced conductivities are achieved for multicomponent systems including a zwitterionic liquid crystal, a lithium salt and propylene carbonate. We describe the development of self-assembled one-and three-dimensional lithium ion conductors composed of zwitterionic liquid crystals, lithium bis(trifluoromethylsulfonyl)imide (LiTFSI) and propylene carbonate (PC). Two types of wedge-shaped zwitterions based on imidazolium dicyanoethenolate and sulfonate were synthesized. These compounds alone show liquid-crystalline (LC) columnar hexagonal (Col h ) phases and low ionic conductivities (10 À8 to 10 À7 S cm À1 ). The increase in the ionic conductivities was achieved by the addition of LiTFSI (10 À5 S cm À1 ) followed by that of PC (10 À4 S cm À1 ). Moreover, LC bicontinuous cubic (Cub bi ) phases are induced by tuning the ionic nature of the zwitterionic liquid crystal with the ratio of LiTFSI and PC. The dissociation of LiTFSI in the zwitterions and the ion-dipole interaction between the lithium ions and PC are shown to be significant keys for the enhancement of the conductivities and stabilization of the nanosegregated LC structures.

“…The chemical structures of the PAA- b -PIL allow the presence of multiple interactions in the self-assembling process, including hydrogen bonds, ionic bonds (electrostatic interactions), hydrophobic interactions and van der Waals interactions. The hydrogen bonding between carboxyl group and the imidazolium ring play an important role in the self-assembly process, as revealed in some previously reported cases69707172737475. The interionic interaction of the pendant ionic groups has been shown to be one of the major parameters for the generation of cubic liquid crystalline structure76.…”

Cubosomes are micro- and nanoparticles with a bicontinuous cubic two-phase structure, reported for the self-assembly of low molecular weight surfactants, for example, lipids, but rarely formed by polymers. These objects are characterized by a maximum continuous interface and high interface to volume ratio, which makes them promising candidates for efficient adsorbents and host-guest applications. Here we demonstrate self-assembly to nanoscale cuboidal particles with a bicontinuous cubic structure by amphiphilic poly(ionic liquid) diblock copolymers, poly(acrylic acid)-block-poly(4-vinylbenzyl)-3-butyl imidazolium bis(trifluoromethylsulfonyl)imide, in a mixture of tetrahydrofuran and water under optimized conditions. Structure determining parameters include polymer composition and concentration, temperature, and the variation of the solvent mixture. The formation of the cubosomes can be explained by the hierarchical interactions of the constituent components. The lattice structure of the block copolymers can be transferred to the shape of the particle as it is common for atomic and molecular faceted crystals.
