  Electroluminescent Properties of Novel Fluorene Derivatives with Aromatic Amine Moieties

  摘要：

  2,7-Bis[(4-diphenylamino)phenylvinylene]-9,9-diethylfluorene(BDPDF, 1) and 2,7-bis[(9-ethyl-3-carbazolylvinylene)-9,9-diethylfluorene(BECDF, 2) have been synthesized and characterized. To evaluate electroluminescent performance, compound 1 and 2 were used as emitting materials and dopant materials, respectively and the basic device structure was ITO/m-MTDATA/a-NPD/1 or 2 or doped DPVBi with 1 or 2/Alq 3 /LiF/Al.The devices using BDPDF(1) and BECDF(2) show EL peak at 470 nm and 486 nm. The device showed a blue light-emission with the CIE chromaticity coordinates of (0.177, 0.268).

  measurements. All the polymers show red‐light emission in the range of 566–656 nm both in solution and in solid state. The quantum efficiency of the polymers was in the range of 56–82%. Among the six polymers synthesized, only polymers containing fluorene units show Tg and polymers based on triphenylamine not exhibit Tg. The band gap of these polymers were found to be reasonably low; hyperbranched copolymer containing

  合成了一系列共轭的超支化聚合物，超支化共聚物和包含2-吡喃-4-亚甲基丙二腈（受体）和三苯胺/芴（供体）单元的线性聚合物，并通过FTIR，1 H NMR，热重分析，差示扫描量热法，凝胶渗透色谱，紫外可见光，光致发光和循环伏安法测量。在溶液和固态下，所有聚合物均显示出566–656 nm范围内的红光发射。聚合物的量子效率在56-82％的范围内。在合成的六种聚合物中，只有含芴单元的聚合物显示出T g，而基于三苯胺的聚合物却没有显示出T g。发现这些聚合物的带隙是相当低的。含芴单元的超支化共聚物的最低带隙为2.18 eV，这是由于吸电子CN基团稳定了LUMO能级。发现聚合物的热和溶解行为良好。器件的所有EL光谱（铟锡氧化物/聚（3,4-亚乙基二氧噻吩）：聚（苯乙烯磺酸盐）/聚合物/ 2,9-二甲基-4,7-二苯基-1,10-菲咯啉/三（8 -羟基喹啉（铝）/ LiF / Al）发出红色光，用P
