**2.1 Materials**

*2.1.1 Synthesis of PNOBDME {Poly[oxy(1,2-dodecane)-oxy-carbonyl-1,4 phenylene-amine-carbonyl-1,4-phenylene-carbonyl-amine-1,4-phenylenecarbonyl]}, (C34H38N2O6)n*

PNOBDME (III in **Figure 8**) was obtained through condensation reaction between 4, 4′-(terephthaloyl-diaminedibenzoic chloride) (NOBC) (II in **Figure 8**) and the racemic mixture of DL-1,2-dodecanediol. Similar notation to precursor cholesteric liquid crystal PTOBDME [16, 17] obtained by a similar method has been used.
