A light emitting device comprising a transparent substrate; a layer of conducting material in contact with the transparent substrate; a self-assembled monolayer bonded to the layer of conducting material; one or more light emitting polymer layers in electron contact to the self-assembled monolayer; and a reflective metal layer in electron contact with the light emitting polymer layer is provided. The light emitting device provided gives enhanced performance as compared to currently available devices. Also provided is a self-assembled monolayer having the formula: R&#x2014;R&#x2014;Y where Y is a group capable of electron contact with a light emitting polymer, Rcontains a conjugated group, and Ris a group capable of bonding to a conducting material.

Light emitting polymer devices using self-assembled monolayer structures

The invention provides LC compositions that exhibit V-shaped switching when aligned in an analog device configuration and exhibit bistability when aligned in a bookshelf-type device configuration. The invention more specifically provides LC compositions of formula 1 and particularly chiral nonracemic compounds of formula 1 which exhibit bistable switching as well as V-shaped switching when aligned in appropriate device configurations. The invention also provides methods of using the compounds of the invention in making LC compositions and electooptical devices comprising an aligned layer of the compositions of this invention.

Partially fluorinated liquid crystal material

Compounds useful as components of LC and FLC compositions which in turn are useful in the manufacture of optical devices. Compounds of this invention have a silane tail, which can contain more than one Si. Compounds of this invention can include those with disilane tails. The invention provides LC compositions containing one or more of the silanes of this invention. Addition of one or more of the compounds of this invention to LC compositions can result in significant improvement in optical or LC properties. In particular, the compounds of this invention can significantly lower the melting point, freezing point or both of an LC composition resulting in significant improvement in device stability.

Alkyl silane liquid crystal compounds

Compounds that are useful as components in liquid crystal compositions, particularly in ferroelectric liquid crystal compositions. Compounds of the invention are rod-like molecules with a mesogenic (generally linear) core to which an alkene tail and an alkyl or alkoxy tail with a perfluoroalkyl terminal portion are bonded. Compounds of the invention can contain a variety of one, two or three ring cores, wherein the rings maybe aromatic or alicyclic. Alkenes of the invention are useful as components to improve LC properties of mixtures, for example, to lower melting point of lower freezing point, of LC compositions.
