Merck KGaA offers reactive mesogens for 3D Film-Patterned Retarders (3D-FPR), which are used in 3D displays.
Therefore, appreciable distortion in the ordered mesogens in the mesophase is not produced.
Performing similar to liquid crystals, licrivue reactive mesogens (RM) are used for 3D displays.
Neeff noted that Reactive Mesogens (RM) are liquid crystalline materials that can be permanently fixed in the liquid crystal phase by polymerization, and can be tailored for UV curing.
Hydroxyaryl ketones are versatile intermediates in the synthesis of biologically active benzoquinone, pesticides, photographic agents, UV absorbents, phenols containing liquid crystal (LC) polymers and low molecular weight mesogens [1-4].
Known synthetic methods for producing these mesogens have relatively low yields and are expensive.
At the upper end of the length scale, Geraldine Bazuin, FCIC, is exploring a supramolecular approach that combines small molecule mesogens with the block copolymers that self-assemble to produce hierarchal structure with meso- and nanoscale features, also amenable to templating nanoscale patterns.
Fact or Fiction: Cybotactic Groups in the Nematic Phase of Bent Core Mesogens
Coupled with phase changes in the curing of LC epoxy resins, curing behavior is influenced by the motions of mesogens and the final network depends on the curing kinetics of the curing reaction (8), (9).
Stilbenes are fluorescent rigid rod mesogens that undergo several photochemical reactions including 2 + 2 photocycloaddition and trans-cis photoisomerization.
Since PS-VA needs specific reactive mesogens liquid crystals, Merck's long-running activities with regard to reactive mesogens for optical compensation films were an important basis for this development - from both a physics and a chemistry standpoint.
Incorporation of bulky pendant mesogens can result in specific linear or nonlinear optical properties (9), (101).
