Abstract

Air-stable and solution-processable fluorene-based bipolar charge transporting materials (CTMs) were designed, synthesized, and analyzed. These CTMs feature anthraquinone, 9-fluorenone, and 9-dicyanofluorenylidine groups and exhibit good film formation properties for solvent processing. Quantum chemistry simulations and optical absorption measurements proved that several stable conformers and charge transfer complexes form inside the molecules. Hole mobilities in CTMs were around 10 to 10 cm V s, while electron mobility in compounds with anthraquinone and 9-dicyanofluorenylidine groups was approximately one order of magnitude lower.

摘要

设计、合成并分析了具有空气稳定性且可溶液加工的芴基双极性电荷传输材料（CTM）。这些CTM具有蒽醌、9-芴酮和9-二氰基亚芴基基团，并表现出良好的用于溶剂加工的成膜性能。量子化学模拟和光吸收测量证明分子内部形成了几种稳定的构象异构体和电荷转移复合物。CTM中的空穴迁移率约为10至10 cm V s，而具有蒽醌和9-二氰基亚芴基基团的化合物中的电子迁移率大约低一个数量级。
