| 中文摘要 | a solution-processable host molecule tpo comprised of hole-transporting triphenylamine and electron-transporting oxadiazole has been synthesized. through meta-linkage between the donor and the acceptor, complete charge localization of the homo and lumo and proper triplet energy are imparted. the new compound shows good thermal stability with a high glass-transition temperature of 131 degrees c. smooth and homogeneous film can be obtained by spin-coating from a tpo/iridium complex blend as probed by atomic force microscopy. the solution-processed red phosphorescent organic light-emitting device (pholed) achieves a maximum current efficiency of 13.3 cd a(-1) with commission internationale de l'eclairage coordinates of (0.64, 0.36); while the green device reaches a maximum current efficiency of 40.8 cd a(-1), and the value is still as high as 39.6 cd a(-1) at a practical luminance of 1000 cd m(-2). the low roll-off can be attributed to the bipolar nature of the host material tpo. an optimized device further elevates the efficiency to 56.8 cd a(-1), which is among the highest ever reported for small-molecule based green pholeds fabricated by a wet |
