| 英文摘要 | on the basis of a well-known hole transporting material, namely 4,4',4 ''-tris(carbazol-9-yl)-triphenylamine (tcta), a series of star-shaped deep-blue fluorescent emitters (2p-tcta, 3p-tcta, 4p-tcta and 5p-tcta) have been successfully developed via a simple extension of the oligophenyl chain between two n atoms. when the number of phenyl rings increases, it is found that both the absorption and emission for these tcta-based starbursts are red-shifted and finally become saturated for 5p-tcta consisting of a pentaphenyl bridge. interestingly, on going from 2p-tcta to 5p-tcta, the film photoluminescence quantum yield is gradually enhanced from 11.4% to 35.5%. the same trend is also observed for their corresponding solution-processed undoped oleds. as a consequence, 5p-tcta shows the best device performance, revealing a maximum luminescence of 7300 cd m(-2), and a peak luminous efficiency of 2.48 cd a(-1) (2.15 lm w-1; 2.30%) together with cie coordinates of (0.15, 0.09). |
