Dedicated to Rhett Emmett.
There has been recent interest in creating new functional materials based on cyclopenta-fused
polycyclic aromatic hydrocarbons (CP-PAH) that can be integrated into organic electronic
devices. These five-membered-ring-containing materials are appealing because the electronic
properties that are associated with their nonalternate PAH ring structure are not
typically accessible by alternate PAH composed solely of six-membered rings. This
paper highlights some recent synthetic advances for new CP-PAH systems and describes
work from our lab that we believe has helped advance the methodology to create new
CP-PAH-containing small molecules and polymeric materials.
Key words
cyclopenta-fused polycyclic aromatic hydrocarbons - cross-coupling - electron acceptors
- donor–acceptor copolymer - organic electronic materials
