Abstract
A glass-forming liquid crystal composition comprises a compound having a molecular weight in the range of about 1000 to 5000 grams per mole and having the formula (NEM)x—CYC—(CHI)y wherein CYC is a substituted cycloaliphatic core moiety containing about 24 to about 60 carbon atoms or a substituted aromatic core moiety containing about 6 to about 36 carbon atoms, NEM is a nematogenic pendant moiety, CHI is a chiral pendant moiety, x is 3 to 9, and y is 0 to 4. An optical device is formed from the liquid crystal composition.
