A new class of star-shaped discotic liquid crystal containing a 2,4,6-triphenyl-1,3,5-triazine unit as a core

A new class of discotic liquid crystals based on 2, 4, 6-triphenyl-1, 3, 5-triazine as a core and [(4-alkoxyphenyl)ethynyl] benzene ester as rigid arms has been synthesized by a Pd(0)/Cu(I)-catalyzed carbon-carbon coupling reaction. The obtained compounds exhibited liquid-crystalline properties.
