The chiral selector L-t-leucine-t-butylamide has been anchored to a polysiloxane by nucleophilic displacement of 2,2,2-trifluoroethyl ester-functionalized block polysiloxanes with L-t-leucine-t-butylamide. Attempts were made to immobilize the chiral polysiloxanes inside the capillaries by thermal treatment at 300 degrees C for 30-90 min. The polysiloxanes were found to be more resistant than Chirasil-Val to the racemization caused by such high temperature treatment. Capillary columns coated with this type of immobilized polysiloxane have shown very high enantioselectivity and thermal stability.
