| 摘 要： | 用Suzuki偶合反应制备了一系列N-(2-乙基己基)-3,6-咔唑(Cz)与4,7-二(4-己基噻吩)-2,1,3-苯并噻二唑(DHTBT)的共聚物, 研究该类聚合物的电化学、光学和电致发光性能. 在薄膜状态下, 即使DHTBT含量为1%的聚合物也发生了从Cz链段到DHTBT单元的有效的能量转移. 光致发光光谱随着DHTBT含量的增加, 从645 nm红移至690 nm. PCzDHTBT1获得了71%的薄膜光致发光效率. 以该类聚合物为发光层的器件的EL光谱也随着DHTBT含量的增加从635 nm红移至680 nm. 由PCzDHTBT15制作的结构为ITO/PEDOT:PSS/polymer/Ba/Al的器件得到了0.61%的外量子效率.

| Abstract: | A series of conjugated copolymers derived from N-(2-ethylhexyl)-3,6-carbazole (Cz) and 4,7-di(4-hexylthien-2-yl)-2,1,3-benzothiadiazole (DHTBT) were synthesized by Suzuki polycondensation. The electrochemical,optical and electroluminescent properties of these polymers were investigated. Effi-cient energy transfer from the Cz segment to the DHTBT unit occurred even if the DHTBT content in the copolymers was as low as 1 mol% in solid film. PL emission was red-shifted significantly from 645 to 690 nm with the increase in DHTBT content from 1 to 50 mol%. The highest PL efficiency in solid film was 71% for PCzDHTBT1. EL emission of devices with these polymers as active layer red-shifted from 635 to 680 nm when the DHTBT content increased from 1 mol% to 50 mol%. The highest external quantum effi-ciency was 0.61% for devices from PCzDHTBT15 with the device configuration of ITO/PEDOT:PSS/polymer/Ba/Al. |
