Abstract The pressure-temperature phase diagrams of OOBAMBC, DOBAMBC and HOBACPC have been determined. All the three compounds exhibit smectic A, C* and I* phases. I*-C*-A* triple points have been observed in OOBAMBC and DOBAMBC at 1.7 kbar and 3.8 kbar respectively. In the case of HOBACPC the range of C* phase decreases with increase of pressure, albeit slowly, and a complete suppression of the C* phase is predicted around 8 kbar.
