Electroluminescent properties of anthracene-containing polyimides

Abstract

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