Conjugated Nanohoops Incorporating Donor, Acceptor, Hetero? or Polycyclic Aromatics

In the last 13 years several synthetic strategies were developed that provide access to [n]cycloparaphenylenes ([n]CPPs) and related conjugated nanohoops. A number of potential applications emerged, including optoelectronic devices, their use as templates for carbon nanomaterials in supramolecular chemistry. To tune structural or properties nanohoops beyond size-dependent effect known [n]CPPs, a variety aromatic rings other than benzene introduced. this Review, we an overview syntheses, properties, [n]CPPs with intrinsic donor/acceptor structure such contain acceptor, donor, heteroaromatic polycyclic units within hoop well nanobelts.
