PAEs Containing Aromatic Units Other Than Benzene in the Main Chain 

In Table 8 all-hydrocarbon PAE backbones are shown, while in Table 9 PAEs with heterocyclic backbones are fisted. Alkyne metathesis is a powerful tool to make poly(fluorenyleneethynylene)s (PFEs, Table 8, entries 1-7). The

The heterocyclic PAEs are useful for low-bandgap applications, as n-type semiconductors, and in sensory applications. Again, as long as the alkynylated or iodinated monomers are available, the synthesis of the corresponding PAE is not a problem, and either the Pd-catalyzed couplings or alkyne metathesis can be utilized toward that end.
