  芴与恶二唑交替共聚物的合成与表征

  摘要：

  通过四唑途径或Suzuki偶联反应已经制备了9，9-二辛基芴和恶二唑的交替共聚物。在聚合物中，恶二唑单元均匀地分散在主链上，每一个P（F 1 - alt -Ox），三个P（F 3 - alt -Ox）或四个P（F 4 - alt -Ox ），芴单元。具有不对称重复单元结构的另一种共聚物P（F 3 -Ox-F 1-Ox）也已准备好进行比较。在这项研究中，与其他恶二唑环形成反应相比，已证明四唑途径为制备具有明确结构的聚恶二唑提供了多个优势。这些优点包括：清洁快速的反应，温和的反应条件，高收率和高分子量的产品。共聚物的玻璃化转变温度在98到150°C的范围内，并且共聚物具有高的热稳定性，分解温度约为430°C。溶液中所有共聚物的紫外可见吸收和光致发光特性与聚（9,9-二辛基芴）相似。在CH 2 Cl 2溶液中，所有共聚物均在蓝光范围内发出荧光，量子产率约为70％。

• Synthesis of dual-emissive organometallic complexes containing heterogeneous metal elements

  We present the dual-emissive dye containing heterogeneous organometallic units. The diad ligand composed of two diketonate moieties linked by fluorene was synthesized. By introducing boron and platinum elements, the emissive molecules were obtained. From optical measurements, it was confirmed that the boron and the platinum-containing diads showed the emissions from the charge transfer and the triplet pi-pi* ligand centered transitions, respectively. Next, to observe these fluorescence and phosphorescence properties from the dye molecule, the diad composed of boron and platinum diketonates linked by the fluorene unit was prepared. Finally, the dual emission containing fluorescence from the boron complex and phosphorescence from the platinum complex was simultaneously observed. (C) 2014 Elsevier Ltd. All rights reserved.

  We present the facile modulation of the optical properties of the conjugated polymers via polymer reactions. The polymers composed of diketonate and fluorene were prepared, and boron complexation was performed after polymer synthesis. By changing feed ratios of BF3 center dot Et2O, which is a reagent to produce a boron diketonate complex, the series of polymers with various complexation ratios with boron at the diketonate unit can be obtained. These synthesized polymers showed diverse optical properties. In the solution states, the quantum yields of emission were greatly changed by the complexation ratios with boron. Accordingly, the polymers with complexation ratio of 21% present the largest intensity. In addition, the emission color can be tuned by changing the complexation ratios in the films. From blue to orange, the emissions were achieved. It was revealed that induced charge transfer between fluorene and boron diketonate should be the main path for the emission of the synthesized polymers.

  tetrazole route or the Suzuki coupling reaction. In the polymers the oxadiazole units were evenly dispersed in the main chain at every one, P(F1-alt-Ox), three, P(F3-alt-Ox), or four, P(F4-alt-Ox), fluorene units. Another copolymer with an asymmetric repeat unit structure, P(F3−Ox−F1−Ox) has also been prepared for comparison. In this study, the tetrazole route has been demonstrated to offer several advantages
