N2 - A high performance chiral selector having the formula: ##STR1## wherein Ar is a monocyclic or ortho-fused polycyclic aromatic moiety having up to 10 ring carbon atoms, either of which may be unsubstituted or substituted with one or more C.sub.1 to C.sub.6 alkyl, C.sub.1 to C.sub.6 alkoxy, NO.sub.2, N(R.sub.5).sub.3.sup.+, CN, COOR.sub.6, SO.sub.3 H and COR.sub.7 groups wherein R.sub.5, R.sub.6 and R.sub.7 are each independently hydrogen or C.sub.1 to C.sub.6 alkyl; PA1 R.sub.1 and R.sub.2 ar each independently hydrogen, C.sub.1 to C.sub.6 alkyl or phenyl; PA1 R.sub.3 and R.sub.4 are each independently C.sub.1 to C.sub.12 alkyl or C.sub.2 to C.sub.12 alkenyl; and PA1 m and n are each independently zero or 1, said compound being an R or an S enantiomer or a mixture of R and S enantiomers.
AB - A high performance chiral selector having the formula: ##STR1## wherein Ar is a monocyclic or ortho-fused polycyclic aromatic moiety having up to 10 ring carbon atoms, either of which may be unsubstituted or substituted with one or more C.sub.1 to C.sub.6 alkyl, C.sub.1 to C.sub.6 alkoxy, NO.sub.2, N(R.sub.5).sub.3.sup.+, CN, COOR.sub.6, SO.sub.3 H and COR.sub.7 groups wherein R.sub.5, R.sub.6 and R.sub.7 are each independently hydrogen or C.sub.1 to C.sub.6 alkyl; PA1 R.sub.1 and R.sub.2 ar each independently hydrogen, C.sub.1 to C.sub.6 alkyl or phenyl; PA1 R.sub.3 and R.sub.4 are each independently C.sub.1 to C.sub.12 alkyl or C.sub.2 to C.sub.12 alkenyl; and PA1 m and n are each independently zero or 1, said compound being an R or an S enantiomer or a mixture of R and S enantiomers.
