Abstract
A homologous series of semifluorinated n-alkanes, F (CF2)(10)(CH2)(m)H, wit h 2 less than or equal to m less than or equal to 19 has been synthesized a nd their properties characterized using a polarising microscope, differenti al scanning calorimetry and X-ray diffraction. The compounds of 6 less than or equal to m less than or equal to 12 exhibit the smectic B phase. The mo lecules from m = 13 to 19 show only a melting endotherm in the DSC traces. Conformational structured are discussed on the basis of ab initio calculati ons.
