Chiral -conjugated organoboron polymers*
A novel π-conjugated organoboron polymer with a chiral side chain was prepared by way of hydroboration polymerization between an optically active diyne monomer and triisopropylphenylborane. The achiral analog of this organoboron polymer was also prepared as reference material. Optical properties and optical activity were investigated by UV–vis absorption, fluorescence emission, and circular dic...
متن کاملMolecularly Imprinted Polymers for the Identification and Separation of Chiral Drugs and Biomolecules
Molecularly imprinting polymers (MIPs) have been extensively applied in chromatography for the separation of chiral drugs. In this review, we mainly summarize recent developments of various MIPs used as chiral stationary phases (CSPs) in high performance liquid chromatography (HPLC), capillary electrochromatography (CEC), and supercritical fluid chromatography (SFC). Among them, HPLC has the ad...
متن کاملChiral separation in microflows.
Molecules that only differ by their chirality, so-called enantiomers, often possess different properties with respect to their biological function. Therefore, the separation of enantiomers presents a prominent challenge in molecular biology and has long been a main pursuit of organic chemistry. We suggest a new separation technique for chiral molecules that is based on the transport properties ...
متن کاملChiral Drug Separation
Consideration of chirality is now an integral part of drug research and development and the regulatory process. There is no choice! Enantiomeric forms of a drug can differ in potency, toxicity, and behavior in biological systems. Enantiomers of all chiral bioactive molecules have to be separated and tested. The Food and Drug Administration (FDA, U.S.A.), and regulatory authorities in Europe, Ch...
متن کاملArt to use Electrospun Nanofbers/Nanofber Based Membrane in Waste Water Treatment, Chiral Separation and Desalination
The technique to fabricate nanofibrous mat by electro-spinning has been known for a long time. But the attempts to use the electospun nanofiber mats, also known as electro-spun nanofiber membranes (ENMs), for filtration purposes began only recently. Among many membrane filtration processes, air cleaning by the removal of dust particles has already been commercialized and the product has been in...
