Patent ID: 8562863

Claim:
A cholesteric glassy liquid crystal composition comprising a compound comprising: a) a core (A) comprising a single ring structure or multi-ring structure, wherein each ring of the single-ring or multi-ring structure independently has 4 to 8 carbons and independently is saturated, unsaturated, or aromatic; b) optionally, 1-10 expander moieties (E) having the following structure: L-ER wherein L is a functional group independently selected in each E moiety from the group consisting of ether, ester, amide, thioether, and thioester, c) wherein ER is a single ring structure or multi-ring structure, and each ring of the single-ring or multi-ring structure independently has 4 to 8 carbons and independently is saturated, unsaturated, or aromatic; and wherein each expander moiety is connected to A via the L group in E; and d) a pendant moiety (Ch) having the following structure: L-chiral spacer moiety-L-nematic moiety) wherein L is independently selected for each occurrence in each Ch group; wherein the chiral spacer moiety comprises from 2 to 15 carbons and at least 1 chiral center; wherein the nematic moiety comprises from 2 to 15 aromatic rings, wherein the number of Ch moieties is from 1 to 20, and wherein each Ch is connected to A directly or via the ER group in E.
