| 中文摘要 | a new host tbu-o-czoxd is facilely synthesized through a simple aromatic nucleophilic substitution reaction between 3,6-di-tert-butyl-9h-carbazole and 2,5-bis(2-fluorophenyl)-1,3,4-oxadiazole. its thermal, electrochemical, electronic absorption and photoluminescent properties are fully investigated. a high glass transition temperature (t-g) of 149 degrees c is observed for tbu-o-czoxd due to the introduction of bulky tert-butyl moiety, significantly higher than 97 degrees c of o-czoxd without tert-butyl substituent. moreover, encapsulation of tert-butyl on the 3- and 6-positions of carbazole greatly enhances the electrochemical stability as compared to o-czoxd. green phosphorescent oleds hosted by tbu-o-czoxd show a maximum luminance of 48293 cd m(-2) at 17.1 v, a maximum current efficiency of 38.4 cd a(-1) and a maximum power efficiency of 34.7 lm w-1. furthermore, the devices exhibit a slow current efficiency roll-off. the device merits, together with the excellent morphological and electrochemical stability, make the new compound an ideal host material for phosphorescent emitters. |
