Ju, Jin Uk published the artcileSynthesis and characterization of a new ethynyl-linked alternating anthracene/fluorene copolymer for organic thin film transistor, Synthetic Route of 18512-55-5, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (2009), 47(6), 1609-1616, database is CAplus.
A new p-type conjugated copolymer, poly(9,10-diethynylanthracene-alt-9,9-didodecylfluorene) (PDADF), which is composed of ethynyl-linked alternating anthracene/fluorene, is synthesized via a palladium(II)-catalyzed Sonogashira coupling reaction with 9,10-diethynylanthracene and 2,7-diiodo-9,9-didodecyl-fluorene. The obtained polymer is confirmed by FTIR, 1H-NMR, 13C-NMR and elemental anal. The PDADF had very good solubility in organic solvents such as chloroform and had a weight average mol. weight of 29,300 with a polydispersity index of 1.29. The PL maximum of the polymer was found at 533 and 568 nm for a solution and 608 nm for film, resp. The HOMO energy of the polymer is -5.62 eV as measured via cyclic voltammetry (CV). A solution-processed thin film transistor device showed a carrier mobility value of 6.0 × 10-4 cm2/Vs with a threshold voltage of -17 V and a capacitance (Ci) of 10 nF/cm2. The out-of-plane and in-plane GIXD pattern of spin-coated polymer on SiO2 dielec. surfaces showed an amorphous halo near 2θ = 20°.
