Abstract

To study the relation of the ordering to molecular shape, molecular dynamics simulation is carried out at the system of coupled Gay-Berne molecules which are dimers of two types of Gay-Berne particles connected by harmonic spring at each end. A strong dependence of the clearing temperature on the bend angle of molecule is derived. Because of the effect of flexible core and also of the mismatching of neighbouring molecules with bend, it is quite hard to obtain monodomain of smectic order.
