[摘要]:Compounds (More Than One Hetero Atom)) Section Two new conjugated macrocycles have been prepd. in high yields using Schiff base condensation. These are the first Schiff base macrocycles to incorporate phenanthrene, and they contain 66 and 78 atoms, resp., in their smallest closed ring. Although the backbones of the two macrocycles have nearly the same constitution, one aggregates in chloroform while the other does not. This is rationalized based on the differential overlap of arom. components in the dimers. |
