摘要：

The feasibility of covalent doping of PPE and PFE with fluorenone utilizing alkyne methathesis was shown. While doping levels of 2-10% showed no effect on solution emission, they are insufficient to ensure complete energy transfer into the dopant sites and lead to efficient orange solid-state emission of these interesting conjugated polymers. Intra- and inter-chain energy transfer caused such a behavior.
