| Novel polar stationary phases were synthesized for use in gas (GC) and supercritical fluid chromatography (SFC). These phases were prepared by hydrosilylation of an alkene onto hydro-containing polysiloxanes or {dollar}alpha{dollar}, {dollar}omega{dollar}-dihydrooligosiloxanes or the polymerization of silane monomers.; Novel chiral stationary phases for use in GC and SFC were synthesized by hydrosilylation of a chiral alkene onto hydro-containing polysiloxanes. A series of chiral copolymeric stationary phases were synthesized using (1R-trans)-1,2-diaminocyclohexane derivatives. The chiral alkenes were hydrosilylated onto {dollar}alpha,omega{dollar}-dihydrooligosiloxanes. Chiral copolymeric stationary phases were also synthesized using phenylglycine and alanine derivatives of (1R-trans)-1,2-diaminocyclohexane. Several of these phases exhibited superior separations of the enantiomers of various chiral diols in SFC. |
