The present invention provides a polymerizable compound having high storage stability without causing crystal precipitation when added to a polymerizable composition. The present invention also provides a polymerizable composition containing the compound. When the filmy polymer produced through polymerization of the polymerizable composition is irradiated with UV light, it hardly discolors or peels from substrate. Further, the present invention provides a polymer produced through polymerization of the polymerizable composition and an optically anisotropic body using the polymer.

There is provided a polymerizable composition, by which discoloration or alignment defects are less likely to occur when a filmy polymer, which is obtained by adding a polymerizable compound to the polymerizable composition and polymerizing this composition, is irradiated with ultraviolet light. There are also provided a polymer obtained by polymerizing the polymerizable composition, and an optically anisotropic body using the polymer. The present invention provides a polymerizable low-wavelength dispersive or polymerizable reverse-wavelength dispersive compound having a partial structure represented by Formula (Z-0). Further, the present invention provides a composition containing the compound; a polymer obtained by polymerizing the composition; and an optically anisotropic body obtained by using the polymer.

The reaction of dilithiated thiophene and thiophene derivatives with group 6 transition metal carbonyl precursors and subsequent alkylation afforded linearly arranged Fischer 2,5-bis-carbene and the rare unsymmetrical 2,3-bis-carbene chelated complexes. The latter requires a second lithiation to occur at an adjacent, less reactive site on the thiophene ring. The control of reactivity sites was investigated

The present invention provides a polymerizable composition containing a specific polymerizable compound and a fluorine-based surfactant having a specific polyoxyalkylene skeleton and having specific molecular weight. The invention also provides an optically anisotropic body, a retardation film, an antireflective film, and a liquid crystal display device that are produced using the polymerizable composition of the present invention. The present invention is useful because, when an optically anisotropic body is produced by photo-polymerization of the polymerizable composition, three features including the leveling properties of the surface of the optically anisotropic body, offset onto the substrate, and liquid crystal alignment can be improved simultaneously.
