Hexabenzocoronene with Swallow-Tailed Substitutes: Synthesis, Characterization and Properties
A hexa-peri-hexabenzocoronene (HBC) derivative, substituted at periphery by six swallow-tailed alkyl chains containing ether linkages, has been synthesized. Its thermal properties and self-organization were investigated using differential scanning calorimetry (DSC) and polarized optical microscopy (POM). Results showed that the peripheral side chains substituted to the aromatic core could lead the HBC to a dramatically lowered isotropization temperature compared with those reported previously, allowing thermal processing at practical temperatures.
