A separate group of such materials are epoxy resins based on liquid crystalline mesogens
, which are used to produce liquid crystalline epoxy networks (LCEN) [1-3, 5, 6].

Hydrosilylation of Mesogens
having carbon carbon double-bonds with poly (methyl hydrosiloxane)s.
Therefore, appreciable distortion in the ordered mesogens
in the mesophase is not produced.

Rainer Neeff of EMD Chemicals discussed "Merck's Reactive Liquid Crystal Materials for Brightness Enhancement Films & Optically Anisotropic Patterned Retarders." 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
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.
Currently, Kornfield says, erasing such CDs calls for annealing in a strong electric or magnetic field, which can require a period of days to realign the mesogens
of a high polymer.
