Bai, Feng published the artcileSynthesis and Characterization of Isoregic Chiral Smectic Polyesters, Recommanded Product: Ethyl 4′-hydroxy-[1,1′-biphenyl]-4-carboxylate, the publication is Chemistry of Materials (1999), 11(7), 1666-1671, database is CAplus.
We prepared a series of isoregic chiral smectic polyesters based on (R)-(-)-4′-{ω-[2-(p-hydroxy-o-nitrophenyloxy)-1-propoxy]-1-alkyloxy}-4-biphenylcarboxylic acid. The head-to-tail (p-hydroxybenzoic acid) type monomers enable us to proceed the isoregically controlled polycondensation. All the monomers exhibited the chiral smectic C and nematic mesophases. The isoregic chiral smectic polyesters have good thermal stability and exhibit monolayered chiral smectic C and smectic A structures.
