Synthesis and Characterization of Fluorene Based Electron Transporting Materials for Polymer Light-Emitting Diodes
We synthesized fluorene based alternating copolymers comprised of several electron withdrawing groups via Suzuki coupling polymerization. Physical properties were characterized using the UV-vis spectroscopy, photoluminescence (PL) spectroscopy. The absorption peaks of copolymers were red-shifted compared to that of corresponding fluorene homopolymer.
