| 中文摘要 | four blue fluorescent host emitters with bifunctional charge transport groups appended to the 9- and 10-positions of the anthracene core have been designed and synthesized. by introducing peripheral bulky aryl-substitution groups to the emissive core, the four compounds show a decreased tendency to crystallise and have high glass transition temperatures ranging from 154 to 226 degrees c. the theoretical calculations reveal that the four self-hosted blue emitters possess noncoplanar structures to suppress intermolecular interaction within the films. the amorphous compounds exhibit strong deep-blue emission both in solution and the solid state. with different end-capping groups, the photophysical and electrochemical properties are tuned to produce efficient deep-blue performance with a simple device architecture. organic light-emitting diodes (oleds) featuring 4 as the emitter achieve a maximum power efficiency of 2.0 lm w(-1) with commission internationale de l'eclairage (cie) coordinates of (0.16, 0.10) that are very close to the national television standards committee's blue standard. the well-matched energy level between the anode and 4 as well as the intrinsic good charge transport abilities results in a very low driving voltage (2.7 v), making the nondoped deep-blue electroluminescent device power efficient. |
