英文摘要A series of solution processible fluorescent dendrimers named PVCt1, PVCt2 and PVCt3 have been designed and synthesized by using 4,4'-distyryl-1,1'-biphenylene as the core and oligocarbazole as the dendron. When the dendron generation grows, the conjugation extension is limited due to the enhanced torsion between core and dendron, and simultaneously the intermolecular interactions can be weakened owing to the dendron encapsulation. As a result, a considerable hypsochromic shift is observed for both the photoluminescence and electroluminescence spectra in nondoped solid states, and the corresponding CIE coordinates move from (0.16, 0.21) of PVCt1 to (0.16, 0.15) of PVCt2 and (0.16, 0.10) of PVCt3. Moreover, compared with the sky-blue PVCt1 (0.82%), the nondoped device based on PVCt3 emits a deep-blue light with an improved external quantum efficiency of 2.81%. These results indicate that the tuning of carbazole-dendron generation can lead to deep-blue distyrylarylene-based fluorescent dendrimers used for efficient nondoped OLEDs.
