Synthesis and catalytic activity of fluorous chiral primary amine-thioureas
Three enantiopure fluorous thioureas featuring a free -NH2 group were synthesized by direct addition of aromatic isothiocyanates bearing a single n-C8F17 substituent in the ortho, meta and para position, respectively, to e
Materials for inducing alignment in liquid crystal and liquid crystal displays
The present invention provides novel aromatic diamines useful in preparing polyimides for optical alignment layers in liquid crystal displays. The novel compositions comprise side-chains general formula I -L1-D-L2-Cf wherein D comprises 1 to 4 carbon-carbon double bonds, Cf is a monovalent C4 to C20 fluorocarbon radical and L1 and L2 are linking groups.

LANGMUIR-BLODGETT FILMS OF POLYALLYLAMINE MODIFIED WITH (PERFLUOROALKYL)PHENYL GROUPS
(Perfluoroalkyl)phenyl groups were introduced to polyallylamine by thiourea bonds.Langmuir-Blodgett (LB) films of the polymers were successfully prepared.Characterization of the films indicated that structural isomerism of substituted benzene has an effect upon the molecular ordering in the LB film and that the limiting area and critical surface tension of the LB films become smaller in the order, ortho, meta, and para isomers.
