  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.

  By using an ultraviolet-curable composition, which contains a specific ultraviolet-curable compound obtained by modifying a bisphenol epoxy compound with a polyester having a flexible structure, as a light transmission layer. Accordingly, the present invention achieves an optical disk having excellent characteristics such as excellent durability, excellent light resistance and excellently reduced warp, while suppressing deterioration of the light reflection film due to environment of high temperature and high humidity or light exposure. Consequently the ultraviolet-curable composition of the present invention is most suitable for optical disks having a thick light-transmitting layer on which recording/reproduction is performed by using a blue laser.
