N2 - The compound 10OHF has a partially inverted phase sequence, unique among the series of nOHF homologous compounds and all other known liquid crystals, with the smectic- C FI2 (Sm C FI2 ) phase occurring at higher temperature than the smectic- C (Sm C) phase. We present ellipsometric data to identify the phase sequences of 9OHF, 10OHF, 11OHF, and 12OHF. Binary mixtures of 10OHF with C11, a compound with the typical phase sequence among the smectic phases, show that the unusual phase sequence of 10OHF stabilizes upon mixing and that Sm C FI2 predominates over Sm C throughout the entire mixing phase diagram. In thin films of some mixtures, surface interactions induce a reentrant Sm C FI2 -Sm C -Sm C FI2 transition in the rest of the film.
