Dynamics and the mesomorphic properties of a novel antiferroelectric liquid crystalline thiobenzoate MHPSBO10: Thermal, optical and dielectric spectroscopy study

► The polymorphism of MHPSBO10 was explored using several complementary techniques. ► Electric field influence on the structure and IR spectrum was probed with DFT. ► Multiple macroscopic properties were studied with electro-optical techniques. ► The molecular dynamics was probed with frequency-domain dielectric spectroscopy. ► A detailed characteristic of the dynamics and the mesomorphic properties was drawn.
