摘要

The P=O bond is strongly polar and electron-withdrawing and a potent coordination agent toward hard cations.Early in1998,Huang and co-workers[1]introduced triphenylphosphine oxide as a co-ligand into a luminescent terbium(Tb)complex for organic light-emitting diodes(OLEDs).Organic phosphine oxide derivatives endowed with luminescence and electron-transport properties have been extensively studied in optoelectronics ever since.Until recently,we have shown that an elegantly engineered electron-transport phosphine oxide is able to afford ultra-stable OLEDs[2].
