Abstract
The synthesis and characterization of the rod-coil oligomer consisting of a molecular rod and a poly(ethylene oxide) with degree of polymerization of 12 (5) are presented. The rod-coil oligomer 5 shows a crystalline phase with microphase segregation. However, the complexation of the rod-coil oligomer 5 with LiCF3SO3 induces a thermotiopic smectic liquid crystalline phase. In aqueous solution, the rod-coil oligomer 5 shows various lyotropic mesophases such as lamellar, cubic and cylindrical micellar mesophases, depending on the oligomer concentration. These results characterized by differential scanning calorimetry and optical polarized microscopy are described.
