Synthesis of Chiral Polyphenylacetylenes Having One-handed Helical Backbone without any Other Chiral Moieties

摘要

[Introduction]Main chains of poly(substituted acetylene)s can take helical conformation and therefore it can become optically active.In this presentation,the four methods we developed to synthesis chiral polyphenylacetylenes having one-handed helical backbone without any other chiral moieties will be shown and compared between them.
