To a suspension of Mg turnings (134 mg, 5.5 mmol) in THF (25 mL), tert-butyl chloride (463 mg, 5.0 mmol) was slowly added via a syringe. After stirring overnight all volatile materials were removed invacuo. The resulting residue was extracted with hot CH2 Cl2. The solution was filter...

This research introduces a novel liquid crystal molecular design approach based on the para-sexiphenyl (6P) structure. Six new liquid crystalline materials were synthesized, incorporating an alkyl terminal and lateral substitutions of the sexiphenyl core to achieve temperature-stable and broad nematic ...
