Key indicators: single-crystal X-ray study; T = 298 K; mean (C-C) = 0.002 Å; disorder in main residue; R factor = 0.045; wR factor = 0.152; data-to-parameter ratio = 11.7.The asymmetric unit of the title compound, C 17 H 18 O 3 , comprises three independent molecules with similar geometries. In each molecule, the carbonyl group is twisted away from the napthalene ring system, making dihedral angles of 1.0 (2), 1.05 (19) and 1.5 (2) . The butene group in all three molecules are disordered over two sets of sites, with a refined occupancy ratio of 0.664 (6):0.336 (6). In the crystal, molecules are oriented with respect to their carbonyl groups, forming head-to-head dimers via O-HÁ Á ÁO hydrogen bonds. Adjacent dimers are further interconnected by C-HÁ Á ÁO hydrogen bonds into chains along the a-axis direction. The crystal structure is further stabilized by weak C-HÁ Á Á interactions.

V599V 4-Methacryloyloxyphenoxy8f 4'-((S)-(+)-ABSTRACT. New two kinds of methacrylate monomers having a benzene ring inserted between spacer and methacryloyl group and the chiral center connected to the terminal of the mesogenic structures were synthesized. In these two series the effects for the formation of the liquid crystals in regard to the length changes of the spacers and mesogenic groups were investigated. The first series did not show any liquid crystalline phases in the intermediate compounds nor in the end products. However, the methacrylates of second series showed the liquid crystalline phases in the intermediate compounds as well as in the final products regardless of the length of the spacers.
