Abstract: We present computer simulations of the Gay–Berne model with a strong terminal dipole. We report the existence of different stable antiferroelectric interdigitated bilayered phases in this model with diverse in-plane organization. The occurrence of these phases depends crucially on the value of the molecular elongation . For = 3 we find an interdigitated bilayered smectic-A phase absent when there is no dipole and a bilayered smectic-T or crystal with positional in-plane tetragonal ordering, different from the hexatic observed in the absence of the molecular dipole. For =4, bilayered smectic-A and in-plane hexatic-ordered smectic-B or crystal phases are observed
