摘要：
A star-shaped organic oligomer, tris(4-(5-(4-(5-(4-(diphenylamino)phenyl)-1,3,4-oxadiazol-2-yl)phenyl)-1,3,4-oxadiazol-2-yl)phenyl)amine, TDPAPOPOPA, based on a N core, containing a hole-transporting arylamine and an electron-transporting 1,3,4-oxadiazole units has been synthesized using a facile multi-step procedure. The star-shaped organic oligomer emits green light with high fluorescence quantum yields (0.92), indicating that the star-shaped organic oligomer is a highly efficient light-emitting material. Reversible anodic oxidation results suggested that the star-shaped organic oligomer should be predominantly hole-transporting. All the results indicate that the synthesized star-shaped organic oligomer is potentially good candidated as bipolar (hole-transporting/electron-transporting) and emitting material for fabrication of organic light-emitting diodes.
