Abstract

Abstract: A facile synthetic strategy towards conformationally stable chiral chromophores based on dimeric porphyrinoids has been established. A peculiar class of face‐to‐face intramolecularly interlocked corrole dimers were formed by the oxidative C−C coupling linked at the inner carbon sites upon simple treatment of copper(II) ions. Their intrinsic electronic structures were modulated by the peripheral corrole ring annulations, which lead to distinct optical properties and redox profiles. The stereogenic carbon centers implemented in the confused corrole skeleton provided a rationale for designing novel chiral materials. Abstract : Asymmetric center in a corrole ring : A series of face‐to‐face orientated bis‐copper corrole dimers were synthesized from the corrole isomers, i. e., N‐confused corroles, upon copper complexation. Peculiar chirality is seen upon the formation of a dimer bearing a stereogenic center. A facile strategy towards conformationally stable chiral chromophores is established.
