中文摘要 | two new host materials, namely dbisipa and doxdsipa, were designed and synthesized by incorporating an electron-donating diphenylamine unit and an electron-accepting benzimidazole or oxadiazole moiety into one molecule via double-silicon-bridged linkage. this extension of molecular structure endows these compounds with good solution processability and high thermal stability without lowering their triplet energies. dbisipa and doxdsipa exhibit similar energy levels and significantly higher glass transition temperatures (146 and 149 degrees c) relative to the corresponding single-silicon-bridged congeners. as a result, solution-processed blue phosphorescent devices employing bis(4,6-difluorophenyl)pyridine-n,c-2')picolinate (firpic) as guest and the two compounds as hosts exhibit high efficiencies with the maximum current efficiency of 16.2 cd a(-1) for dbisipa and 15.2 cd a(-1) for doxdsipa. these efficiencies are significantly higher than those of the control blue device employing typical nonconjugated polymer, poly(9-vinylcarbazole) (pvk), as the host, and even comparable to those of the complicated control device employing pvk doped with 30 wt % 1,3-bis[(4-tert-butylphenyl)-1,3,4-oxadiazolyl]phenylene (oxd-7) as the mixed host. |
