Abstract
The transition temperatures and phase diagrams of five fluorinated benzylidenaniline derivatives have been studied by TM and X-ray diffraction techniques. A smectic polimorphism appears in all compounds. The structure of smecticB phases has been deeply studied in order to evidence a possible utilization of such phases as solvents able to exert stereochemical effects on polimerization reactions. The parameters of theSB hexagonal lattice area=b=4.29 A in all the studied compounds, whilstc varies from 18.9A to 24A as a function of the C atom number of the alkyl chain; its averaged increase is 1.265A for each CH2 group. In any case, the distance between the smectic planes is equal to the molecular length so that interdigitated structures are to be excluded.
