| 中文摘要 | a novel phosphonate substituted 4,4'-bis(n-carbazolyl)biphenyl (cbp), namely pcbp, has been designed and successfully synthesized by an indirect palladium catalyzed suzuki-miyaura reaction. x-ray crystallography analysis from a pcbp single crystal demonstrates that there is a hydrogen bond interaction between the two adjacent molecules due to the presence of phosphonate, which promotes their one-dimensional line arrangement along the c-axis. compared with the prototype cbp (-5.55 ev), in addition, the highest occupied molecular orbital (homo) level of pcbp is reduced to -6.00 ev, leading to a large hole injection barrier. on the other hand, the introduction of phosphonate substitutes can endow pcbp with excellent electron injection/transport ability. as a result, pcbp shows an electron-dominated behaviour observed in single carrier devices, which is different from the hole-dominated one for cbp. such a transition is then used to tune the single-layer device performance of a self-host phosphorescent dendrimer, and the peak luminous efficiency significantly increases from 1.7 cd a(-1) of cbp to 31.4 cd a(-1) of pcbp. |
