  Synthesis and Properties of Poly(10-Octylphenothiazine-CO-2′,3′,6′,7′-Tertrakis-Octyloxy-9-Spirobifluorene) for OLEDs

  摘要：

  Many attempts have been focused on polymer light-emitting diodes ( PLEDs) for large area display application. We report synthesis and properties of new phenothiazyl polymer derivatives, Poly(10-octyl-10H-phenothiazine-3,7-diyl) ( POP), Poly( 20,30,60,70-tertrakis-octyloxy-9-spirobifluorene-2,7-diyl) ( PTOSF), and their random copolymers, Poly( 10-octylphenothiazine-co-20,30,60,70- tertrakis-octyloxy-9-spirobifluorene) ( POTOSF), which were polymerized by Yamamoto reaction. The obtained compound was identified by H-1- NMR, UV- Visible spectroscopy and GPC data. Weight average molecular number ( Mn) of the polymers ranged from 17,000 to 300,000 g= mol with polydispersity indices of 1.6 similar to 6.5. Maximum UV-Visible absorption of the polymers was distributed from 285 to 403 nm. PL emission of POP, PTOSF and POTOSF copolymer were found to be 480, 434 and 484 nm, respectively. EL emission peak of double- layer EL device of POTOSF was at 494nm ( bluish green).

• Poly(spirobifluorene)s Containing Nonconjugated Diphenylsulfone Moiety: Toward Blue Emission Through a Weak Charge Transfer Effect
  作者：Xuchao Wang、Lei Zhao、Shiyang Shao、Junqiao Ding、Lixiang Wang、Xiabin Jing、Fosong Wang

  Instead of conjugated dibenzothiophene-S,S-dioxide (DBTSO), we have introduced nonconjugated diphenylsulfone (DPSO) as the electron-deficient unit into the main chain of poly(spirobifluorene)s (PSFs). Because of the weaker electron affinity of DPSO relative to DBTSO, the charge transfer from the pendant 2,3,6,7-tetraoctyloxyfluorene to the main chain can be effectively prevented. Consequently, the resultant polymers containing DPSO moiety show pure blue emissions, which is different from DBTSO-based PSFs that exhibit undesired green emissions. With a single-layer device configuration, a peak luminous efficiency of 2.90 cd/A and a maximum luminescence of 14130 cd/m(2) have been realized for the polymer PSFDPSO03. The corresponding CIE coordinates are (0.17, 0.18), nearly independent of the applied current density from 2 to 592 mA/cm(2). These results indicate that tuning the electron affinity of the incorporated electron-deficient units is a very promising strategy to control the charge transfer strength for the development of blue-emitting PSFs with high efficiency and stability.
• Modular Access to 9,9-Spirobifluorenes by Oxidative Coupling Using Molybdenum Pentachloride

  DOI：10.1055/s-0033-1338297

  日期：——

  The strong oxidizing agent molybdenum pentachloride was used for an efficient direct C-C bond formation of 9,9-diarylfluorenes to the corresponding 9,9-spirobifluorenes. Thus, a versatile method that is compatible with labile groups, such as iodo moieties, was established. By this approach important building blocks for light emitting polymers were synthesized in high yields.

  An organic light-emitting device includes a first electrode, a second electrode, and an organic layer interposed between the first electrode and the second electrode. The organic layer includes at least a light-emitting layer, wherein the light-emitting layer includes a plurality of compounds which have individually a light-emitting repeating unit and at least one of a hole-transporting repeating unit and an electron-transporting repeating unit and which are different in the molar ratio of the light-emitting repeating unit and at least one of the hole-transporting repeating unit and the electron-transporting repeating unit, and wherein the plurality of the compounds are stacked so that the molar ratio of the hole-transporting repeating unit may decrease and/or the molar ratio of the electron-transporting repeating unit may increase in the direction from the first electrode toward the second electrode. The hole transport capability of the light-emitting layer decreases in the direction from the first electrode toward the second electrode and the electron transport capability of the light-emitting layer decreases in the direction from the second electrode to the first electrode. Therefore, hole transport and electron transport are equilibrated, thereby ensuring high efficiency and long lifetime.
