Electroluminescent properties of anthracene-containing polyimides

Optical and electroluminescent properties of a new soluble anthracene-conta ining polyimide (ACPI) was studied. Solubility of ACPI in organic solvents allows direct spin casting of the polymer films exhibiting in tense photo- and electroluminescence (EL) in the visible range. This non-conjugated poly mer was used as emitting and electron-hole transporting layers in polymer l ight-emitting devices (LEDs). EL properties of the uni- and bilayer LEDs av e discussed in terms of the band structure, bipolar transport and electron donor-acceptor interactions. Copyright (C) 2000 John Wiley & Sons, Ltd.
