Synthesis and studies of blue light emitting polymers containing triphenylamine-substituted fluorene and diphenylanthracene moiety

Authors


Abstract

Photoluminescent (PL) polymers containing triphenylamine-substituted fluorene and diphenylanthracene (DPA) units were synthesized by aromatic nucleophilic substitution reaction. The light emitting polymers (LEPs) contains hole-transporting triphenylamine (TPA) groups at the C-9 position of fluorene and DPA-emitting segments in the main chain. The obtained polymers were soluble in various organic solvents and thermally stable. The synthesized polymers were successfully characterized by elemental analyses, FTIR and, 1H NMR spectroscopy. The electrochemical measurements and optical properties of the polymers were also studied. The obtained polymers showed significant blue emission. © 2011 Wiley Periodicals, Inc.
