| 20080274304 | Functionalized Photoreactive Compounds - The present invention concerns functionalized photoreactive compounds of formula (I), that are particularly useful in materials for the alignment of liquid crystals. Due to the adjunction of an electron withdrawing group to specific molecular systems bearing an unsaturation directly attached to two unsaturated ring systems, exceptionally high photosensitivities, excellent alignment properties as well as good mechanical robustness could be achieved in materials comprising said functionalized photoreactive compounds of the invention. | 11-06-2008 |
| 20080293888 | Photocrosslinkable Materials - A diamine compound of formula (I) is proposed as well as polymers, copolymers, polyamic acids, polyamic acid esters, or polyimides based on such compound. | 11-27-2008 |
| 20090136687 | TOPOLOGICALLY STRUCTURED POLYMER COATING - Sub-micron-structured (nanostructured) polymer film or coatings are made by coating a substrate with a mixture of materials. One of the materials is removed using a selective solvent, leaving pores or other nanostructure. The substrate may be grooved, providing a competing nanostructure. The coating may act as an antireflective coating, optical retarder, optical diffuser, or orientation layer. | 05-28-2009 |
