Abstract

Laterally ligated p-terphenyl twins containing 2-oxapropylene spacers have been synthesized. Their liquid-crystalline properties were investigated by polarizing microscopy, calorirnetry and X-ray scattering. The mesophase stability depends strongly on the topology of connection. It was found that the connection of the mesogenic units at the peripheries of the rigid cores gave twins with the highest clearing temperatures and the broadest smectic ...
