Abstract
  • The synthesis of new random poly(2,7-fluorenylene-vinylene)s was achieved by a Suzuki-Heck cascade polymerization reaction. The poly(fluorenylene-vinylene) base structure was modified by the regio-random incorporation of 1-cyano-2,5-phenylene as electron withdrawing unit (CN-PFV1) and its properties were compared with terpolymers also embodying 1,4-dioctyloxy-2,5-phenylene (CN-PFV2) or 3,6-N-octylcarbazole (CN-PFV3) as electron-donating moieties. Thermal analysis revealed a high thermal stability (T-d > 389 degrees C) and the absence of glass transitions for all polymers. Cyclic voltammetry indicated a high electron affinity of the materials (2.96-3.21 eV) attributed to the presence of the cyano-containing comonomer. In dilute solutions, the copolymers showed a broad green fluorescence with quantum yields ranging from 0.42 to 0.79, while in the solid state, a relatively narrow emission centered at similar to 560 nm, governed by the low-energy segments within the pi-conjugated backbone, was observed. The electroluminescence properties of the materials were tested in OLED devices of ITO/PEDOT-PSS/CN-PFV1-3/Ca/Al or ITO/PEDOT-PSS/CN-PFV1-3/Alq(3)/Ca/Al configurations, showing a bright green-yellow emission that, in the case of CN-PFV2, reached 1403 cd/m(2) with efficiencies as high as 0.13 cd/A.
