New fluorene-based light emitting polymer was synthesized from nickel-catalyzed Yamamoto coupling reaction of 2,7-dibromo-9,9’-bis-2-ethylhexylfluorene with a carbazole based monomer. The polymers was well characterized by UV-vis spectra, PL and EL spectra, 1H and 13C NMR, elemental analysis, and TGA. EL device was fabricated by spin-coating onto ITO and its structure was ITO/PEDOT-PSS/polymer/LiF/Al. In this presentation, we report new fluorene-based copolymer and its possibility of introducing to blue light emission.{image1} |
