RESUMO
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/pi interactions and remarkably accelerate syn-anti conformational change of the 2,2'-bipyrrole components leading to helicity change in the figure eight loop of [32]octaphyrins.
