Formation of smectic mesophases in binary systems of short chain alkanoic acid salts

Comparison of the Ionic Liquid Crystal Phase of [C12C1im][BF4] and [C12C1im]Cl by Atomistic MD Simulations

“…− and a C22 alkyl chain is needed for the case of bistriflimide ((CF 3 SO 2 ) 2 N − ) anion [29]. A similar behavior is observed in metal alkanoates: when the anion bearing the alkyl chain is paired with larger cations (e.g., from Li + to Cs + ) a longer alkyl chain is needed in order to observe the formation of ILC phases [30][31][32].…”

Lithium–thallium(i) butyrates binary system: an intermediate salt and liquid crystal from non-mesogenic compounds.

“…The clearing of this ILC phase appears here as an invariant, as it happens in the LiC5 + TlC5 system, 18 but different to other apparently similar phase diagrams reported ([LiC4 + CsC4] or [LiC4 + RbC4]). 29,30 Polarizing light microscopy was used to identify the liquid crystal phase as ''smectic A-like'' or neat phase. In Fig.…”

“…18 Many binary phase diagrams have been analyzed 28 with the aim of finding new mesogenic phases or enlarging an existing thermotropic LC phase in the binary phase diagram. Some of the phase diagrams between short alkanoates with different-sized metals have shown stable mesogenicity, such as [LiCn + CsCn] 29 (where n = 2, 3 and 4), or [LiC4 + RbC4]. 30 Others have shown a stabilization of the mesophase (increasing the range of temperature and composition at which the liquid crystal phase is stable), like [LiC5 + TlC5].…”

Liquid Crystals and Glasses in Binary Systems from Sodium and Alkali-Earth Metal Butyrates

“…Many alkali short-chain alkanoates and their binary mixtures form so-called ionic liquid crystals or mesophases [1][2][3][4]. But there are no data on binaries of alkanoates with asymmetrically charged metal cations, such as univalent alkali and divalent alkaliearth metal cations.…”
