Table 1 and Figure 1shows the phase transition behaviour of S-Bi6 at different mol% in the mixed system. At 0 mol% of S-Bi6 (only 5CB), clearing point was found at around 35 °C. After increasing mol% of S-Bi6, it was found that S-Bi6 in the mixed system at 1, 5, 10 and 15 mol% had 2 phase transitions that were chiral nematic and isotropic phase; the clearing point was risen and the gold complex was stabilized in chiral nematic phase. However, crystalline phase and phase separation between isotropic of 5CB and crystalline phase of S-Bi6 was happened at 20 and 25 mol% of S-Bi6.
