supermolecules is studied by DSC, and results are shown in Fig. 18. Phase transition
information is summarized in Table 4. From these results, samples 13–15 only form
glasses, and no liquid crystalline phases are observed. This can be attributed to the
short tail length of C5. On the contrary, samples 16–18 can exhibit liquid crystalline
phases.
