摘要

Abstract

The anionic polymerization of

-vinylcarbazole (NVC) by using optically active anionic initiators such as the lithium salts of (

)-1-(9H-fluoren-2-yl)-4-isopropyl-4

5-dihydrooxazole ((

)-1-FIDH) and (

)-2-(9H-fluoren-2-yl)-4-isopropyl-4

5-dihydrooxazole ((

)-2-FIDH) and complexes of (-)-Sparteine with n-butylithium (

-BuLi-(-)-Sp) or fluorenyl lithium (FILi-(-)-Sp) was achieved. The yield and specific rotation of poly(

-vinylcarbazole)s (poly(NVC)s) were considerably affected by the molar ratio of (

)-FIDH to NVC. The highest yield and specific rotation were obtained with Li-(

)-1-FIDH as an initiator

with a molar ratio of monomer and initiator [M]/[I]

= 10/1. The effects of the chiral initiators

type of solvent and the polymerization temperature were investigated. The obtained optical activity of polymers was attributed to asymmetric induction of the chiral initiators.
