The surface tension of freestanding liquid-crystal films has been measured as a function of film thickness and temperature. The data are independent of film thickness from over 100 down to only two molecular layers (≊ 50 Å) and no temperature dependence could be detected. The results obtained on recently synthesized partially fluorinated materials indicate that the film-vapor interfaces consist of roughly equal proportions of [Formula Presented] and [Formula Presented] terminal groups.
