Abstract:
Disclosed are a vinylsulfone derivative, a liquid crystal composition comprising the same, and a compensation film for a liquid crystal display device using the same liquid crystal composition. More particularly, the vinylsulfone derivative is a liquid crystal material of a high-quality view angle compensation film, which improves a contrast ratio measured at a tilt angle when compared to a contrast ratio measured from the front surface and minimizes color variations in a black state depending on view angles.
Abstract:
New chemical reactions of 1,1,2-trifluoro-1,3-butadiene provide simple access to a series of new fluorinated alkene derivatives. These derivatives provide a simple, general methodology for the stereocontrolled preparation of 2-fluoro-2-alkenoate esters and related monofluoroalkene derivatives which include fluoro analogs of known insecticides, pheromones or pharmaceuticals. A new method for the preparation of 1,1,2-trifluoro-1,3-butadiene is also provided.
