Polymerization of N-vinylcarbazole in the presence of organic salts with chiral or stereodifferentiating ligands

Organic salts as initiators [A*B-+(-): Ph(3)*C+ClO4-, Ph(3)*C+SbCl6-, (-)Sp*(ClO4-)-Cl-+, and (-)(Sp)*(3+)(2)(ClO4)(3)(-)] and catalysts [A(+)B*(-): (+)CSA*; A*B-+*(-): ph(3)*C+(+)CSA*(-) and (-)Sp*(+)(+)CSA*(-)] are prepared and characterized by the dissociation constant (K-d), fraction of free ions (alpha), and specific rotation. The asymmetrically stereoselective induction of the initiators and catalysts in the polymerization of N-vinylcarbazole is in the order A*B-+*(-) > A(+)B*(-) > A*B-+(-). The specific rotations of the poly(N-vinylcarbazole) (PVCZ)s obtained are generally in this order.
