  Carbazole/fluorene copolymers with dimesitylboron pendants for blue light-emitting diodes

  摘要：

  A series of random and alternating carbazole/fluorene copolymers with various dimesitylboron-containing carbazole derivative contents were synthesized by Suzuki polymerization for use as a light-emitting layer in blue light-emitting diodes. Two carbazole derivatives, CzPhB and CzPhThB consisted of a carbazoyl group as the donor and a dimesitylboron group as the acceptor group, separated by phenyl and phenyl-thiophene groups pi-conjugated systems, respectively. The copolymers exhibited good thermal stability and blue emission in both solution and the solid state. Moreover, the CzPhB/fluorene and CzPhThB/fluorene copolymers exhibited a higher PL quantum efficiency than the fluorene-based homopolymer (POF). Higher brightness and larger current efficiency were observed for the CzPhB/fluorene and CzPhThB/fluorene copolymer-based devices compared to the POF-based device. Additionally, the CzPhThB/fluorene copolymer-based devices had better EL performances than the CzPhB/fluorene copolymer-based devices. The turn-on voltage, maximal brightness, and highest luminescence efficiency of the carbazole/fluorene copolymer-based devices were found to be 4.5-8.5 V. 436 cd/m(2), and 0.51 cd/A, respectively.

  Triarylboranes are widely used as luminescent molecules. However, there are few reports focused on thermally activated delayed fluorescence (TADF) characteristics. In this study, new donor-acceptor triarylboranes exhibiting TADF characteristics are designed, synthesized, and applied to organic light-emitting diodes (OLEDs) as an emitter.

  三芳基硼烷被广泛用作发光分子。但是，很少有报道关注热活化延迟荧光（TADF）特性。在这项研究中，设计，合成具有TADF特性的新型供体-受体三芳基硼烷，并将其作为发射体应用于有机发光二极管（OLED）。仅用两步就可以合成与咔唑（7），9,9-二甲基ac啶（8）和吩恶嗪（9）连接的电子接受二甲苯乙烯基苯基硼烷，收率很好。化合物8和9表现出浅蓝色和绿色TADF，在甲苯中的PL量子产率分别为89％和87％。另一方面，化合物7显示正常的深蓝色荧光，没有TADF特征。密度泛函理论和随时间变化的密度泛函理论研究表明，施主单元的高电子供电能力以及交联亚苯基与施主单元之间的大二面角是由于HOMO和LUMO在空间上分开，从而降低了能隙在最低的单重态（S 1）和三重态（T 1）激发态之间，激子从T 1到S 1态的反向系统间交叉加速。使用化合物8和9作为发射体的OLED呈现浅蓝色和绿色发射，具有非常好的外部量子效率，分别为16
