Fluoroalkylfluorene derivatives

A charge transporting, liquid crystal photoalignment material comprising a charge transporting moiety connected through covalent chemical bonds to a surface derivatising moiety, and a photoalignment moiety connected through covalent chemical bonds to a surface derivatising moiety.

Liquid crystal photoalignment materials

Display devices using feedback-enhanced light emitting diodes are disclosed. The display devices include but are not limited to active and passive matrix displays and projection displays. A light emissive element disposed between feedback elements is used as light emitting element in the display devices. The light emissive element may include organic or non-organic material. The feedback elements coupled to an emissive element allow the emissive element to emit collimated light by stimulated emission. In one aspect, feedback elements that provide this function include, but are not limited to, holographic reflectors with refractive index variations that are continuous.

OLED materials having the formula: T-A(-S-B(-P-B)m-S-A)n-T where A are independently selected rod-shaped, rigid molecular core units, S are independently selected flexible spacer units, B are polymerisable crosslinking groups independently selected, P are spacer groups independently selected, T are independently selected end groups, m are independently selected from values of from 1 to 4, n is equal to I to 3.

Oligomeric organic light emitting diode (OLED) materials containing multiple crosslinking functions

A charge transporting, liquid crystal photoalignment material comprising a charge transporting moiety connected through covalent chemical bonds to a surface derivatizing moiety, and a photoalignment moiety connected through covalent chemical bonds to a surface derivatizing moiety.

Methods of producing OLED materials containing fluorene ring systems in which two alkyl substituents at the 9-position of fluorene ring are alkyl substituted through key intermediates generically represented by the formula: where X represents a substituent that increases the acidity of the hydrogen atoms on the adjoining methylene group (which is immediately adjacent the fluorene ring systems 9 -position). 

Methods for producing organic light emitting diode (OLED) materials

A non-coherent light emitting device having at least one organic light emitting or organic charge transporting layer and a structure providing a Bragg grating associated with the light emitting layer is described. The organic light emitting layer having liquid crystalline material is treated to provide alternating zones of isotropic and liquid crystalline material. The combination of alternating zones with the dichroic effects of the aligned zone produces a pseudo 2-D Bragg grating within the light emitting layer.
