中文摘要	a series of blue-emitting poly (2,7-carbazole) s substituted with n-phenylcarbazole (bczpcz01-bczpcz10) have been synthesized via suzuki polymerization. by reducing the loading of pd catalyst from 10 parts per thousand to 1 parts per thousand, their number-average molecular weights are correspondingly increased from 27000 to 69000 while their polydispersity indexes (pdi) remain in the range of 2. 5 to 3. 0. and the effect of the molecular weight on their photophysical, electrochemical and device properties is then thoroughly investigated for these obtained polymers. most importantly, the introduction of rigid n-phenylcarbazole can effectively tune the interchain interactions, and improve the color purity of blue emission. as a result, all the polymers show film photoluminescent quantum yields as high as 0. 40 and excellent spectral stability, for no green emission often appeared in polyfluorenes is observed here under annealing or electric field conditions. single layer polymer light-emitting diodes are fabricated with a configuration of indium tin oxide (ito)/poly(3,4-ethylenedioxythiophene) : poly (styrene sulfonic acid) (pedot: pss)/polymer/ca/al. among these polymers, bczpcz01 exhibits a peak luminous efficiency of 0. 33 cd/a with commission internationale de l' eclairage (cie) coordinates of (0. 18, 0. 12). the device performance is improved by about 65% in comparison to that of poly (2, 7-carbazole) s substituted with triphenylamine. these interesting results will provide a novel platform for the design of highly efficient stable blue-emitting polymers in the future.
