The nOHFBBB1M7 (n=10) compound, 10OHF, shows a reversed Sm C FI2 -Sm Cphase sequence, unique among all known antiferroelectric liquid crystals. This reversed phase sequence is stabilized when 10OHF is doped with 9OTBBB1M7(C9) or 11OTBBB1M7(C11). In contrast, doping of the homologous members (n=9, 11, or 12) eliminates the Sm C FI2 phase. One 10OHF/11OHF mixture without the Sm C FI2 phase was selected for further studies. By adding C9 into this particular mixture, the reversed phase sequence is revived. To our surprise, even though 11OHF destabilizes the Sm C FI2 phase in binary mixtures with 10OHF, it significantly increases the Sm C FI2 temperature range in the 10OHF/11OHF/C9 ternary mixtures.
