  用于高效溶液加工绿色 PHOLED 的具有高三线态能量的烷基芴基可交联空穴传输材料

  摘要：

  具有高三重态能量 ( E T ) 的空穴传输材料 (HTM)是高效磷光有机发光二极管 (PHOLED) 所必需的，因为它们可以有效地阻止三重态激子在发光层中的反向传输。此处，两个基于烷基芴核的可交联 HTM，4,4'-(9,9-二丙基-9 H -fluorene-2,7-diyl)bis( N -phenyl- N -(4-vinylphenyl)苯胺) ( V-PFPDPA ) 和 4,4'-(9,9-dihexyl-9 H -fluorene-2,7-diyl)bis( N -phenyl- N -(4-vinylphenyl)aniline) ( V-HFPDPA ), 被设计和合成。由于固有的高E T在芴核心结构中，发现V-PFPDPA和V-HFPDPA具有理想的E T分别为 2.72 eV 和 2.73 eV，因此有利于抑制激子猝灭。交联的空穴传输层具有高热稳定性和优异的耐溶剂化性。所得溶液处理的绿色

  A series of bis(3,6-di-tert-butylcarbazol-9-ylphenyl)aniline end-capped oligoarylenes, BCPA-Ars, are synthesized by double palladium-catalyzed cross-coupling, reactions. By using this bis(carbazol-9-yl)triphenylamine moiety as an end cap, we are able to reduce the crystallization and retain the high emission ability of these planar fluorescent oligoarylene cores in the solid state, as well as improve the amorphous stability and solubility of the materials. The results of optical and electrochemical studies show that their HOMOs, LUMOs, and energy gaps can be easily modified or fine-tuned by either varying the degree of pi-conjugation or using electron affinities of the aryl cores which include fluorene, oligothiophenes, 2,1,3-benzothiadiazole, 4,7-diphenyl-4-yl-2,1,3-benzothiadiazole, and 4,7-dithien-2-yl-2,1,3-benzothiadiazole. As a result, their emission spectra measured in solution and thin films can cover the full UV-vis spectrum (426-644 nm). Remarkably, solution-processed nondoped BCPA-Ars-based OLEDs could show moderate to excellent device performance with emission colors spanning the whole visible spectrum (deep blue to red). Particularly, the RGB (red, green, blue) OLEDs exhibit good color purity close to the pure RGB colors. This report offers a practical approach for both decorating the highly efficient but planar fluorophores and tuning their emission colors to be suitable for applications in nondoped and solution-processable full-color emission OLEDs.
