The research purpose is the application of chiral organocatalysts to the precise synthesis of well-defined polymers. The ring-opening of racemic lactide was carried out using (R)-(-)-3,3'-bis(pentafluorophenyl)-1,1'-binaphthyl-2,2'-diyl- phospholic acid as the organocatalyst to produce the high enetioselective living polymerization leading to optically active poly(lactide).

研究目的是应用手性有机催化剂来精确合成明确的聚合物。以(R)-(-)-3,3'-双(五氟苯基)-1,1'-联萘-2,2'-二基磷酸为有机催化剂,使外消旋丙交酯开环生成高对映选择性活性聚合产生光学活性聚丙交酯。
