中文摘要	a series of novel yellow-emitting electrophosphorescent polymers (phps) have been designed and synthesized by grafting a 2-(fluoren-2-yl)-1h-benzoimidazole ligand based iridium complex, (fbi)(2)ir(acac), with a fluorinated poly(arylene ether phosphine oxide) backbone (fpczpo). due to the efficient intermolecular forster energy transfer from fpczpo to (fbi)(2)ir(acac) and charge trapping on (fbi)(2)ir(acac), the electroluminescence from fpczpo is almost completely quenched, even if the ir complex content incorporated into the polymer is as low as 2 mol%. it is found that the polymer exhibits the best device performance when the ir loading is optimized to 3 mol%. a peak luminous efficiency of 10.4 cd a(-1) with commission internationale de l'eclairage coordinates of (0.53, 0.46) is achieved, which is superior to that of the previously reported yellow phps with polyfluorene as the main chain. the result indicates that the fluorinated poly(arylene ether phosphine oxide) is a promising scaffold for the construction of efficient yellow phps.
