Significance

Here, the authors are able to ­demonstrate the high efficiency of zirconocene-mediated coupling of dialkynes via the synthesis of macrocycles 2 and 3. The orientation of the anthracene units into the plane of the macrocycle leads to the strained architecture. The high utility of this methodology should also lead to its further use in the design of new nanoscopic organic structures.
