Different substituent groups were introduced onto the rim of β-cyclodetrin through rigid C=N or CH
2
-N=C bonds to form a
series of imino-modified β-cyclodextrin derivatives, and bonded to silica gel to obtain chiral stationary phase(CSPs), which
were applied in high-performance liquid chromatography (HPLC). The separation performance of these CSPs was examined
with a variety of different rac-amino acids, -secondary alcohols, -ferrocene derivatives, and chiral drugs under the polar organic
and the reversed phase modes. Excellent enantioseparations were achieved for most of the analytes. The results demonstrated
that the former CSPs was more effective for rigid analytes and the latter for flexible molecules, and for selectors containing ionic
segements better chiral separation was observed with the highly polar and even ionic analytes. The essential differences between
the driving force factors and function mechanism of chiral recognition were elucidated through investigating and comparing the
differences of separation performance among these analytes.
