  • Poly(diphenylacetylene) compound, preparation method therefor, and use thereof as optical isomer separating agent
    Patent number: 9290592
    Abstract: The present invention provides an optical isomer separating agent and a production method thereof. That is, the present invention provides a one-handed helical poly(diphenylacetylene) compound represented by the following formula (I) [wherein each symbol is as described in the DESCRIPTION], and a production method thereof, an optical isomer separating agent containing the poly(diphenylacetylene) compound, and a packing material for a chiral column, containing the optical isomer separating agent coated on a carrier. Since these have a superior separation ability for a wide variety of compounds, a practical optical resolution method can be provided.
