  Facile Modulation of Optical Properties of Diketonate-Containing Polymers by Regulating Complexation Ratios with Boron

  摘要：

  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.

  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.
