A hydrogen-bonded supramolecular hexagonal columnar liquid crystal composed of a tricarboxylic triphenylene and monopyridyl dendrons
Tricarboxylic triphenylene (TPC5) and monopyridyl dendron (DenC12) were mixed in 1:2, 1:3, and 1:4 molar ratios, and investigation by IR, DSC, and XRD studies proved that TPC5 and DenC12 self-assembled to form a hexagonal columnar liquid crystal with 1:3 molar stoichiometry via complementary hydrogen-bonds.
