METHOD FOR PHASE-TRANSFER OF INORGANIC COLLOIDAL SEMICONDUCTOR NANOCRYSTALS Russian patent published in 2016 - IPC B01J13/00 B82B3/00 B82Y40/00 C07B57/00 C07B61/00 B22F1/00 C09K11/54 C09K11/56 C09K11/88 

FIELD: chemistry.

SUBSTANCE: invention can be used in chemistry, biology and medicine for imaging and diagnosis. Colloidal inorganic semiconductor nanocrystals are transferred from organic to aqueous phase, not miscible with organic phase, using a phase transfer catalyst. Phase-transfer catalyst used is enantiomers chiral molecules. Phase-transfer process is carried out at temperature in range of 0-4 °C. Semiconductor nanocrystals are transferred from organic phase into aqueous phase, which have same type of chiral property as used enantiomer of phase-transfer catalyst.

EFFECT: invention allows separation of enantiomers of inorganic colloidal semiconductor nanocrystals by enantioselective phase transfer.
