  接枝有环金属化铱配合物和电荷传输部分的聚芴的高效红光发射

  摘要：

  我们报告了一种设计电致发光聚合物的新途径，通过将作为掺杂剂和电荷传输部分的高效磷光有机金属络合物接枝到具有单层/单聚合物的聚合物发光二极管 (PLED) 的全共轭聚合物的烷基侧链上。所研究的聚合物体系包括聚芴 (PF) 作为基础共轭聚合物，咔唑 (Cz) 作为电荷传输部分和通过与 PF 主链形成电复合物而产生绿色发射源，以及作为磷光的环金属化铱 (Ir) 配合物掺杂剂。除了来自PF主链的能量从绿色Ir配合物或芴主链和侧链咔唑部分之间形成的电复合物转移到红色Ir配合物之外，还可以显着提高器件性能，

  By selecting polyfluorene as the polymer host, choosing 2,1,3-benzothiadiazole derivative moieties as the red dopant units and covalently attaching 0.3 mol% of the dopant units to the side chain of the polymer host, we developed a novel series of red electroluminescent polymers of dopant/host system with molecular dispersion feature. Their EL spectra exhibited predominant red emission from the dopant units because of the energy transfer and charge trapping from the polymer backbone to the dopant units. The emission wavelength of the polymers could be tuned by modifying the chemical structures of the dopant units. Single-layer devices (device configuration: ITO/PEDOT : PSS/polymer/Ca/Al) of these polymers emitted red light with a peak at 615 nm, a luminous efficiency of 5.04 cd A−1 and an external quantum efficiency of 3.47%, or emitted deep-red light with a peak at 650 nm, a luminous efficiency of 1.70 cd A−1 and an external quantum efficiency of 2.75%. Their high EL efficiencies were due to the energy transfer and charge trapping from the host to the dopant units as well as the molecular dispersion of the dopant units in the host. Increase of the dopant unit content led to increased turn-on voltages and decreased EL efficiencies of the resulting devices.

  通过选择聚氟烯作为聚合物宿主，选择2,1,3-苯并噻二唑衍生物作为红色掺杂单元，并将0.3 mol%的掺杂单元共价连接到聚合物宿主的侧链上，我们开发了一系列具有分子分散特性的红色电致发光掺杂/宿主体系聚合物。它们的电致发光光谱显示，掺杂单元产生的红色发光主要是由于聚合物主链向掺杂单元的能量转移和电荷捕获。通过修改掺杂单元的化学结构，可以调节这些聚合物的发射波长。这些聚合物的单层器件（器件结构：ITO/PEDOT:PSS/聚合物/Ca/Al）发出了峰值为615nm的红光，光效为5.04 cd A−1，外部量子效率为3.47%；或者发出了峰值为650nm的深红光，光效为1.70 cd A−1，外部量子效率为2.75%。它们的高电致发光效率归因于宿主到掺杂单元的能量转移和电荷捕获，以及掺杂单元在宿主中的分子分散。掺杂单元含量的增加导致开启电压上升和器件电致发光效率下降。

  We developed a series of highly efficient blue electroluminescent polymers with dopant–host systems and molecular dispersion features by selecting 1,8-naphthalimide derivatives as the light blue emissive dopant units, choosing polyfluorene as the deep blue emissive polymer host and covalently attaching the dopant units to the side chain of the polymer host. The polymers' EL spectra exhibited both deep blue emission from the polymer host and light blue emission from the dopant units because of the energy transfer and charge trapping from the polymer host to the dopant units. By modifying the chemical structures of the dopant units, we controlled the energy transfer and charge trapping from the polymer host to the dopant units and consequently tuned the emission colors of the resulting polymers. Thermally annealed single-layer devices (ITO/PEDOT/polymer/Ca/Al) based on these polymers emitted deep blue light with a luminous efficiency of 2.89 cd A−1, a power efficiency of 2.01 lm W−1 and CIE coordinates (0.16, 0.17), or emitted sky-blue light with a luminous efficiency of 6.84 cd A−1, a power efficiency of 4.28 lm W−1 and CIE coordinates (0.15, 0.22). Their excellent EL performances were due to the energy transfer and charge trapping from the polymer host to the highly fluorescent dopant units.

  我们选择 1,8-萘二甲酰亚胺衍生物作为浅蓝色发光掺杂单元，选择聚芴作为深蓝色发光聚合物宿主，并将掺杂单元共价连接到聚合物宿主的侧链上，从而开发出一系列具有掺杂宿主体系和分子分散特性的高效蓝色电致发光聚合物。由于从聚合物主链到掺杂单元之间的能量转移和电荷捕获，聚合物的电致发光光谱同时显示出聚合物主链的深蓝色发射和掺杂单元的浅蓝色发射。通过改变掺杂单元的化学结构，我们控制了从聚合物宿主到掺杂单元的能量转移和电荷捕获，从而调整了所得聚合物的发射颜色。基于这些聚合物的单层器件（ITO/PEDOT/聚合物/Ca/Al）经热退火后发出深蓝色光，发光效率为 2.89 cd Aâ1，功率效率为 2.01 lm Wâ1，CIE 坐标为 0.16，0.17；或发出天蓝色光，发光效率为 6.84 cd Aâ1，功率效率为 4.28 lm Wâ1，CIE 坐标为 0.15，0.22。它们出色的电致发光性能得益于从聚合物基体到高荧光掺杂单元的能量转移和电荷捕获。
