Polyfluorene is a polymer with formula n, consisting of fluorene units linked in a linear chain — specifically, at carbon atoms 2 and 7 in the standard fluorene numbering. It can also be described as
This is the photoluminescence of two very similarly structured polyfluorene derivatives. The one on the left (purple) is a copolymerization of a fluorene derivative, benzene and oxadiazole molecules and the one on the right (light green) has the structure directly below this image.
