Abstract: A charge transporting or light emitting polymer may be formed from one or more reactive mesogens where the one or more reactive mesogens have the formula: B—S-A-S—B wherein A is a chromophore, S is a spacer, and B is an endgroup with the general formula wherein R1=an alkyl group or an aryl group, R2=an alkyl group, an aryl group, or H, and R3=an alkyl group, an aryl group, or H. The polymer may be formed by photopolymerization which occurs at fluence levels of 10 joules/cm2 or less.

Abstract: A method of forming a layer including mixing at least a first material and a second material to form a mixture, depositing the mixture on a surface, and polymerizing the mixture to form a polymer network. The polymer network being at least one of charge-transporting or luminescent has improved properties as compared to the first and second materials including the rate of polymerization, the power level, time, and/or amount of energy per unit of mass used for polymerizing. The polymer network may be formed on an alignment layer that is unrubbed such as a photoalignment layer. The polymer network may be fabricated with uniform structure and thickness. The polymer network may have a liquid crystal phase and includes few dangling radicals and molecular fragments.

Abstract: The present invention relates to charge transporting or light emitting polymerizable materials having photocrosslinkable dienes. These materials may be polymerized to form charge-transport or light emission layers. The diene substituted materials include small molecules, oligomers, and polymers that are either of liquid crystalline or non-liquid crystalline nature. The present invention also provides materials formed from polymerizing the charge transport or light emitting polymerizable materials, processes of forming the polymers, and devices using the polymers.
