From blue fluorescence to red fluorescence: Solid-state oxidative coupling polymerization of fluorene and anthracene or naphthalene

Through the solid-state oxidative coupling polymerization, a series of fluorene-co-anthracene copolymer (PFA) and fluorene-co-naphthalene copolymers (PFN) were synthesized using FeCl3 as the oxidant. The structures of the copolymers were characterized by FT-IR and 1H NMR spectra, showing the random...
