“…Thermochemical behaviour of more than 3000 organic compounds known to behave as liquid crystals can be found in the review published by Acree and Chickos in 2006 . After a careful revision of that paper taking into account requirements one, two and three, it has been found that various homologous liquid crystal series or families (A–F) resulted to fulfill them . In Figure , clearing point enthalpy for each compound of these series has been represented versus the corresponding clearing temperature.…”

SUMMARYThe development of thermal storage systems adapted to processes in which steam is involved is currently increasing because no cost-effective solution is available to date. Entailing water condensation and evaporation, isothermal storage under latent heat is the most appropriate approach. The low thermal conductivity of the materials currently in use significantly affects both power density and power generation of the storage system in discharge. In order to solve these drawbacks, the use of liquid crystals as alternative storage materials is proposed because they can absorb/release energy at constant temperature and at the same time keep the ability to flow. In this way, liquid crystals with clearing points close to the saturated steam working temperature and high enthalpy of mesophase-isotropic liquid transition would be required. The main advantage of using liquid crystals as storage materials is that convection would be the heat transfer mechanism and power would be constant with time during discharge processes.

“…Terphenyl cores are more popular over the biphenyls and quaterphenyls because of their higher optical anisotropy over the former and lower transition temperatures over the latter [7][8][9]. The two F-substituents at the 3,39-positions are utilized to suppress the melting point of the potential ferroelectric liquid crystal close to the room temperature, with minimum increase in the viscosity.…”
