摘要：
An alcohol-soluble and ion-free small molecule TPPO functionalized with phosphonate groups has been developed as the electron transporting material for multilayer PLEDs fabricated via an orthogonal solvent strategy. A state-of-art current efficiency as high as 11.6 cd A(-1) is achieved, which is about 16 times higher than that of the single-layer device without TPPO (0.7 cd A(-1)).
