An extraordinary and universal matter state arises from ions and polar molecules in strict/quasi-1D structures, beyond solids, liquids, and gases

Almost all existing one-dimensional materials belong to quasi-one-dimensional materials, beset with constraints in composition, fabrication, structural stability, and applicability. Based on the "universal dual-limit temperature control method," this paper employs molecular dynamics simulations and first-principles calculations to investigate typical systems of ions and mixed ionic-polar molecular systems. Remarkably, it uncovers a universal extraordinary state of matter featuring strictly one-dimensional and quasi-one-dimensional structures formed by ions and polar molecules, beyond solids, liquids, and gases. This discovery significantly expands our understanding of material structures in terms of elemental composition, spatial structure, dimensionality, distribution, and stability, opening up a new, unknown frontier for research at atomic and mesoscopic scales. In this realm, chloride and sodium ions intricately weave into spiral or curved ionic chain networks by individually linking up in space. These networks gracefully accommodate various types of ions in diverse ratios. When temperatures rise, polar molecules and ions spatially segregate, giving rise to ionic columns or clusters. This non-liquid state, bearing some liquid-like attributes, defies traditional solid-state physics. Its mesoscopic structure, boasting atomic precision, promises to reveal novel electrical, optical, acoustical, thermal, and mechanical phenomena, serving as a cornerstone for theoretical frameworks and experimental pathways in the preparation and study of new structures. The phenomena, concepts, methodologies, and principles presented in this paper delve into the depths of fundamental science, enriching our understanding of material structures and unlocking unprecedented possibilities in material science, nanotechnology, atomic manufacturing, and energy conversion. These findings are poised to catalyze advancements in multiple disciplines and exert a profound impact on society.
