  Self-Organization of Rod−Coil Molecules with Layered Crystalline States into Thermotropic Liquid Crystalline Assemblies

  摘要：

  The synthesis and characterization of the rod-coil molecules of ethyl 4-[4-[oxypoly(propyleneoxy)-propyloxy]-4'-biphenylcarboxyloxyl]-4'-biphenylcarboxylate with poly(propylene oxide) coil of 7 (7-P-4), 8 (8-P-4), 10 (10-P-4), 12 (12-P-4), 15 (15-P-4), 17 (17-P-4), and 20 (20-P-4) propylene oxide units are described. The introduction of poly(propylene oxide) (PPO) coils with different lengths into the rodlike mesogen gives rise to a rich self-assembled microstructures. In the crystalline state, the rod-coil molecules with 7-12 repeating units of PPO organize into a microphase separated monolayer lamellar structure in which rods are fully interdigitated. In contrast, the rod-coil molecules with 15-17 repeating units of PPO exhibit a lamellar structure with rod tilt relative to the layer normal. A dramatic mesophase change is observed with the variation of the coil length. The rod-coil molecules 7-P-4 and 8-P-4 with short PPO coils display layered smectic C and smectic A mesophases, while the rod-coil molecules 10-P-4, 12-P-4, and 15-P-4 with medium-length coils exhibit a biconticuous cubic mesophase with Ia3d symmetry. Further increasing the length of coils as in the cases of 15-P-4, 17-P-4, and 20-P-4 induces a hexagonal columnar mesophase. Estimations based on the lattice parameters and densities have shown that the organization of the rod-coil molecules into a cross sectional slice of a cylinder for the cubic and columnar phases can give rise to an aromatic core with a square cross section. This unique behavior in the rod-coil molecules is believed to originate from the anisotropic aggregation of rod segments and consequent entropic penalties associated with coil stretching.
