However, from the thermal perspective, these materials present a high potential for thermal energy storage applications in solid-state due to their heat storage capacity during their phase transitions. Here, we evaluate the first-order transition of these materials from the molecular point of view and make a relation with organic size, which is responsible for the ordering-disordering transition. Six LHOIPs have been synthesised, (C12H25N)2CuCl4, (C14H29N)2CuCl4, (C16H33N)2CuCl4, (C12H24N)2MnCl4, (C14H29N)2MnCl4 and (C16H33N)2MnCl4, where the crystal transformation has been evaluated under X-ray diffraction and Raman, and thermal conductivity as well as the thermal expansion have been studied. This work provides a comprehensive evaluation of the disordering phenomenon that is produced during phase transitions8 p.application/pdfengcc-by-nc-nd (c) Salgado Pizarro, Rebeca, et al., 2024http://creativecommons.org/licenses/by-nc-nd/4.0/Espectroscòpia RamanCiència dels materialsEmmagatzematge d'energiaRaman spectroscopyMaterials scienceStorage of energyinfo:eu-repo/semantics/article7505462025-12-19info:eu-repo/semantics/openAccess
