Naproxen-based chiral compounds and liquid crystal display applications

A liquid crystal comprising a compound of formula (I):

• wherein,
• R1 is (C2-C20)alkyl, (C2-C20)alkenyl, or (C2-C20)alkynyl;
• R2 is (C2-C20)alkyl, (C2-C20)alkenyl, or (C2-C20)alkynyl;
• Q1 and Q2 are each hydrogen, or together Q1 and Q2 are oxo (═O) or thioxo (═S);
• Z is O—C(═O), C(═O)O, CH2O, CH2CH2, OCH2, or is absent;
• X is oxy (—O—), O—C(═O), C(═O)O, CH2O, CH2CH2, OCH2, or is absent;
• Y is oxy (—O—) or thio (—S—);
• R0 is an aromatic ring system, a cyclic ring system, a hetero aromatic ring system, a hetero cyclic ring system, or a combination thereof;
• each bond represented by - - - - - - is independently optionally present;
• any one or more of the aromatic ring system, cyclic ring system, hetero aromatic ring system, hetero cyclic ring system, or combination thereof of R0 is optionally substituted on carbon with one or more halo;
• any one or more of the (C2-C20)alkyl, (C2-C20)alkenyl, or (C2-C20)alkynyl of R1 and R2 is optionally substituted on carbon with one or more halo;
• and
• any one or more of the (C2-C20)alkyl, (C2-C20)alkenyl, or (C2-C20)alkynyl of R1 and R2 is optionally interrupted with one or more oxy (—O—), thio (—S—), Si(RA)(RB) or Ge(RARB), wherein each RA and RB is independently (C1-C6)alkyl or (C1-C6)alkenyl.
