A series of AA/BB-type supramolecular polymers (SP1–3) based on pillar[5]arene host–guest interactions was developed and their photoelectric properties were further evaluated. The formation of SP1 was confirmed by multiple measurements via nuclear magnetic resonance and specific viscosity studies. The electroluminescence properties of SP1–3 were also investigated. As a result of the efficient energy transfer caused by the exciton trapping on narrow band gap guest G2, by applying a doping strategy, the light-emitting color of the resulting polymers could be easily turned from blue to green. Meanwhile, photoluminescent efficiencies up to 81.6% were obtained. All the supramolecular polymers prepared in this work were utilized as the emissive layers (EMLs) in light-emitting devices and a maximum luminance efficiency (LE) of nearly 5 cd A^–1 was achieved.

基于柱[5]芳烃的荧光超分子聚合物用于OLED器件制造

开发了一系列基于柱[5]芳烃主-客体相互作用的AA/BB型超分子聚合物（SP1-3），并进一步评估了它们的光电性能。SP1 的形成通过核磁共振和比粘度研究的多次测量得到证实。还研究了 SP1-3 的电致发光特性。由于激子俘获在窄带隙客体 G2 上引起的有效能量转移，通过应用掺杂策略，所得聚合物的发光颜色可以很容易地从蓝色变为绿色。同时，获得了高达81.6%的光致发光效率。在这项工作中制备的所有超分子聚合物都被用作发光器件中的发射层 (EML)，最大发光效率 (LE) 接近 5 cd A^达到–1。
