Control of Conformation and Chirality of Nonplanar π-Conjugated Diporphyrins Using Substituents and Axial Ligands.

Abstract

Nonplanar conformations of pyrazine-fused Zn(II) diporphyrins could be controlled by the choice of the meso-aryl substituents and an axial ligand on the central metals. Zn(II) diporphyrins bearing sterically demanding meso-aryl groups with ortho-substituents led to a twisted chiral D2 conformation, while an achiral C2h form was preferred in the case of aryl… (More)
