Its photophysical, electrochemical and electroluminescent characteristics were primarily studied. The made single-emissive-layer (SEL) polymer light-emitting devices using (dfppy)2Ptz(CsOXT)2 as emitter exhibited a satu- rated red emission peaked at 620 nm. The best device performances were obtained in the device at 8 wt% dopant concentration, with a maximum external quantum efficiency of 8.4%, a current efficiency of 4.2 cd/A and brightness of 3228 cd/m~. This work provides an effective approach to obtain high-efficiency red emission through construction of new binuclear platinum complex and its doped SEL devices.展开更多
