| Sumario: | Layered hybrid organic-inorganic perovskites (LHOIPs) have gained specific attention in applications such as optoelectronics. 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 transitions |
