| 中文摘要 | novel compound (bcbp) based on the modification of a well-known host material 4,4'-(bis(9-carbazolyl))biphenyl (cbp) through arylmethylene bridge linkage was synthesized, and fully characterized. its thermal, electrochemical, electronic absorption and photoluminescent properties were studied. a high glass transition temperature (t-g) of 173 degrees c is observed for bcbp due to the introduction of the bridged structure, remarkably contrasting with a low t-g of 62 degrees c for cbp. furthermore, the bridged structure enhances the conjugation and raises the homo energy, thus facilitating hole-injection and leading to a low turn-on voltage in an electroluminescent device. with the device structure of ito/moo3/npb/ir complex: bcbp/bcp/alq(3)/lif/al, maximum power efficiencies of 41.3 lm/w and 6.3 lm/w for green- and blue-emitting oled were achieved, respectively. |
