Abstract
The PL and EL properties of a novel light-emitting alternating copolymer co mposed of triphenylamine (TPA) and phenylene vinylene derivate (MEHPPV), th at is, TPA-MEHPPV and its blend with PVK were demonstrated. A considerable enhancement of the EL intensity was observed by using the polymer blends as the emission layer in the organic light-emitting devices (OLEDs). The ener gy transfer process in the polymer blends was also discussed. (C) 2001 Else vier Science B.V. All rights reserved.
