Anisotropic derivatives of (-)-L-lactic acid and their nanocomposites

Three in one: Mesogenic aromatic acid as a liquid crystal matrix, a chiral dopant in liquid crystals and a stabilizer for nanoparticles

“…The choice of that compound is dictated by the following reason: several chiral lactic acid derivatives have been studied before [25,26] and their liquid crystal structure was proven. We have reported in [25] on the synthesis of derivatives of natural chiral Llactic acid namely by the interaction of the corresponding substituted hydroxybiphenyls, hydroxyterphenyls and hydroxyquaterphenyls with (-) ethyl L-lactate.…”

“…R-MPA(1)) was prepared from the corresponding 3,6-disubstituted cyclohex-2-enone (4) according to published methods [24][25][26] . The schema of the synthesis of mesogeniclike R-MPA is given in Figure 1.…”
