Alignment and directional ionic transport in liquid-crystalline and related ordered soft electrolytes: a 25-study evidence map with an architecture-aware comparability audit

Abstract: Directional ionic transport is widely reported in liquid-crystalline and related ordered soft electrolytes, but a conductivity ratio has no fixed meaning unless the alignment, transport axis, specimen history, and measurement architecture are reported together. This public-source evidence map examined 25 primary studies across ionic liquid crystals, liquid-crystalline polymers, proton-conductive networks, gels, and related ordered soft materials. Each record was assessed for experimental alignment evidence, an explicit axis convention, reporting of both directions, matching of material and measurement conditions, source-located numerical information, and the experimental relationship between the two directional measurements. Nineteen records provided direct alignment evidence, 24 defined a transport axis, 23 reported both directions, 12 met the initial condition-matching rule, and ten retained an exact sourcelocated numerical directional pair for audit. These reporting counts do not constitute a common quantitative dataset. A focused architecture audit of six high-information records applied a conservative rule requiring one specimen, one measurement architecture, matched conditions, and source-located directional values. None met all requirements: four compared separately prepared orientation states and two compared different cell designs. The result does not negate directional transport. It shows that directional evidence, orientation-state sensitivity, and crosscell sensitivity answer distinct experimental questions and should not be merged into a pooled anisotropy. The paper therefore provides a structured map of the field, identifies the reporting links that prevent quantitative synthesis, and proposes a minimum disclosure framework for future directional-transport studies.
