Abstract: Two HBC derivatives (HBC-C13 and HBC-C15), both containing 6 odd-carbon alkyl chains surrounding the rigid plane core, were investigated as discotic liquid crystal. The difference between their thermal behaviors has been investigated by using differential scanning calorimetry (DSC). Their mesomorphic phase behavior was observed by polarizing optical microscopy (POM). A remarkable odd-even effect in the phase transition temperatures was observed for all HBC derivatives (HBC-C12, HBC-C13, HBC-C14, HBC-C15 and HBC-C16).

Abstract: A new HBC derivative HBC-C17 containing 6 odd-carbon alkyl chains surrounding the hexabenzocoronene core was synthesized, and investigated as discotic liquid crystal along with HBC-C13 and HBC-C15. The thermal behaviors have been investigated by using differential scanning calorimetry (DSC). And mesomorphic phase behavior of HBC-C17 was observed by polarizing optical microscopy (POM). A remarkable variation in the phase transition temperatures was observed for these three HBC derivatives (HBC-C13, HBC-C15 and HBC-C17). Moreover, the mesomorphism of these HBC derivatives can be compared with HBC-C12, HBC-C14 and other HBCs with even carbon alkyl chains, meanwhile the relationship between the length of substitutes and thermal properties of HBCs is also studied.
