Abstract

Abstract An effective method to stabilize oligocarbynes as a modelfor polycarbyne by the simultaneous complexation withα-cyclodextrin (α-CD) is described. 1, 12-Bis (9-phenanthryl)- 1, 3, 5, 7, 9, 11-dodecahexayne possessing one or two α-CD molecules was prepared by the oxidative coupling reaction of the corresponding triyne in the presence of α-CD. The resulting rotaxanes proved to be stable enough in comparison with the corresponding free ...
