초록

An alternating copolymer of PPV and PTV, poly[2-methoxy-5-(3,7-dimethyl)octyloxy-1,4-phenylenevinylene-alt-2,5-thienylenevinylene] (DAPPV-PTV) has been synthesized and light-emitting properties of the polymer have been studied. A single layer EL device using DAPPV-PTV as an emitting layer between ITO and Al electrodes (ITO/DAPPV-PTV/Al) has been fabricated, and light emission of the device becomes visible at 3 V. The EL emission maximum of the device is about 620 nm. Double layer EL device using DAPPV-PTV and Alq3 (ITO/DAPPV-PTV/Alq3/Al) has also been fabricated. The double layer EL device shows two-color emission depending on the applied voltage. The device emits a pale green color from 8 V, and then the color turns to red at about 18 V.
