title: Donor-acceptor segregated paracyclophanes composed of naphthobipyrrole and stacked fluoroarenes.
abstract: The expeditious synthesis of donor-acceptor segregated paracyclophanes has been achieved by a selective SNAr reaction of hexafluorobenzene with o-dipyrrolylbenzenes and subsequent cyclodehydrogenation. An orthogonally arranged D-A segregated structure was confirmed by X-ray crystallography. The combined results of DFT calculations and absorption spectra revealed the charge transfer (CT) nature from the naphthobipyrrole (donor) to the stacked fluoroarene moiety (acceptor).
