摘要：

(Figure Presented) Across the great divide: Substituents located opposite one another in meso positions on a [26]hexaphyrin scaffold are forced into close contact through a dynamic conformational change. A simple aryl group and an ethynyl group in these positions undergo a [3+2] annulation reaction either upon thermal activation or spontaneously to provide indenylene-bridged macrocycles that can serve as ligands for mixed-valence complexes (see structures). © 2007 Wiley-VCH Verlag GmbH & Co.
