Jow, Kenny G.; Dingemans, Theo J. published the artcile< Liquid crystals derived from 2-phenylisoindoles: synthesis and characterization>, Formula: C8H3BrO3, the main research area is phenylisoindole preparation smectic A liquid crystal.
2-Phenylisoindole was studied as the rigid core unit in asym. mesogenic mols. When the 2-phenylisoindole core was terminated with a hexyl tail, no mesophase formation could be observed When 4-(tridecafluorohexyl) was used, however, both monotropic and enantiotropic phase behavior were observed Most functionalities at the anhydride 5-position gave smectic A (SmA) phases in the temperature range 70-180°. Functionalities at the anhydride 4-position suppress mesophase formation. Large substituents (Br, NO2) and sym. substitution patterns (5,6-dichloro, 4,7-dichloro and 4,5,6,7-tetrachloro) on the anhydride moiety increase the m.p. and destabilize the mesophase. Temperature dependent x-ray diffraction experiments suggest an interdigitated SmA packing for this family of compounds
