Encouraged by theoretical predictions that nematic phases formed from V-shaped compounds could be biaxial, shape-persistent phenylene ethynylene arms linked by 1,3-phenylene, 4,4′-diphenylenemethane and 3,6-fluorenone units have been synthesized. Crystall

2-Bromo-5-iodo-hydroquinone dialkylethers are prepared by the stepwise halogenation and alkylation of hydroquinone monoalkylethers using simple and easily performable reactions. Boron tribromide induced cleavage of the dipropoyl ether gives the parent com
