Abstract: On the basis of a fluorinated poly(arylene ether phosphine oxide) backbone with both high triplet energy and appropriate HOMO/LUMO levels highly efficient all-phosphorescent single white-emitting polymers were designed and successfully synthesized via a "two-step addition" strategy. Simultaneous blue and yellow triplet emissions were achieved to generate white electroluminescence with a promising luminous efficiency as high as 18.4 cd/A (8.5 lm/W 7.1%) and CIE coordinates of (0.31 0.43).
