Synthesis of Soluble Fluorene‐polyimino Ketone

Abstract

Based on the 9,9-di(4-anilinyl)fluorene, structurally different fluorene-polyimino ketones have been obtained by the Buchwald-Hartwig cross coupling reaction. Their structure and performance have been characterized by FT-IR, 1 H NMR, UV-vis and thermal analysis. The results show an agreement with the proposed structure, which possesses high glass transition temperature (T g ＞250 ℃) and good thermal stability with high decomposition temperatures in nitrogen atmosphere (T D ＞520 ℃). Additionally, the polymers synthesized showed good solubility, which can be dissolved in common organic solvent CHCl 3 at room temperature.

Synthesis of Carbazoled Poly(<i>Arylene Imino</i>)

“…Poly(imino ketone)s were considered the most promising class of polymers due to their outstanding physical properties. In order to obtain serious of high-performance polymers with good optical properties, poly(imino ketone)s containing fluorine (PIKF) have been prepared [8][9][10]. The problem of PIKF is its poor hole-transporting abilities.…”

Synthesis and properties of poly(arylene imino) containing fluorenone group (PIKF)

“…Typical applications would be conceivable in photovoltaic cells or in multilayer light-emitting diodes (LED) [7] . In this paper, the aim is to synthesize novel conjugated non-conjugated PIKF polymers containing novel carbon-nitrogen linkage as electron-deficient polymers via palladium-catalyzed polycondensation [8][9][10] . An extensive characterization of the PIKF polymers in terms of gel permeation chromatography (GPC), polymer solubility, thermal behavior (TG), differential scanning calorimetry (DSC), UV-vis absorption spectra, photoluminescence will be investigated.…”
