| 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. |
