Shape-persistant macrocycles with terpyridine units: Synthesis, characterization, and structure in the crystal

Grave, Christian,Lentz, Dieter,Schaefer, Andreas,Samori, Paolo,Rabe, Juergen P.,Franke, Peter,Schlueter, A. Dieter

, p. 6907 - 6918 (2007/10/03)

The synthesis of a variety of shape-persistent macrocycles with either one (1a-d, 2) or two (opposing) terpyridine units (3, 4, 5a-c) and inner diameters of up to 2 nm is described. The sequences are mainly based on transition metal cross-coupling reactio
