本课题所研究的是含有多聚苯刚性分子片段的金鸡纳碱类手性催化剂。
This paper focuses on the synthesis of cinchona alkaloid catalysts which contains rigid polybenzene moieties and their application in asymmetric catalytic reactions.
CMC由长且刚性的分子组成,由于大量电离的羧基,这种刚性分子存在负电荷。
Since CMC consists of long, fairly rigid molecules that bear a negative charge due to numerous ionized carboxyl groups, electrostatic repulsion causes its molecules in solution to be extended.
