- W3152149065 abstract "A new silole monomer with two 4-(N,N-dimethylamino)phenyl substitutions on silicon atom was designed and synthesized. Three copolymers PF-N-HPS1, PF-N-HPS10 and PF-N-HPS20 were then obtained by copolymerizations of 2,7-fluorene derivatives with the silole monomer at feed ratios of 1%, 10%, and 20%. Their UV-vis absorption, electrochemical, photoluminescent, and electroluminescent (EL) properties were investigated. PF-N-HPS possessed HOMO levels of 5.25–5.58 eV, and showed green emissions. Using PF-N-HPS as the emissive layer, three different polymer light-emitting diodes were fabricated as device A with ITO/PEDOT/PF-N-HPS/Al, device B with ITO/PEDOT/PF-N-HPS/Ba/Al, and device C with ITO/PEDOT/PF-N-HPS/TPBI/Ba/Al. For the device A, PF-N-HPS only showed very low EL efficiency of 0.1–0.33 cd/A, indicating that the Al cathode could not inject electron efficiently to the emissive polymers containing the 4-(N,N-dimethylamino)phenyl groups. For the device B, low work function Ba supplied better electron injections, and the EL efficiency could be improved to 0.85–1.44 cd/A. TPBI with a deep HOMO level of 6.2 eV could enhance electron transport and hole blocking. Thus modified recombinations and largely elevated EL efficiency of 4.56–7.96 cd/A were achieved for the device C. The separation of the emissive layer and metal cathode with the TPBI layer may also suppress exciton quenching at the cathode interface." @default.
