Dynamic Figure Eight Loop Structure of meso-Tetraaryl[32]octaphyrins(1.0.1.0.1.0.1.0)

3,3′-Diethyl substituents of the 2,2′-bipyrrole components in meso-tetraaryl[32]octaphyrins(1.0.1.0.1.0.1.0) affect the cavity shape through CH/π interactions and remarkably accelerate syn−anti conformational change of the 2,2′-bipyrrole components leading to helicity change in the figure eight loop...
