title: Tetrachloro-tetra(perylene bisimides): an approach towards N-type graphene nanoribbons.
abstract: An extraordinarily large pi system based on tetrachloro-tetra(perylene bisimides) with very broad absorption spectra from the UV to the NIR region and an extremely strong electron-accepting ability has been synthesized from tetrachloro-di(perylene bisimides).
