Four substituted nonacenes were prepared and characterized by UV-vis and EPR spectroscopy and X-ray crystallography. The compounds are the most stable and soluble nonacenes to date - due to six strategically placed triisopropylsilyl(TIPS)-ethynyl groups. They are stable for several weeks in the solid state. In dilute solution their half-life is 5-9 h. Crystal structure analyses of two nonacenes prove their structures. A nonacene derivative was tested in a solution-processed transistor and exhibits ambipolar charge transport (μ =0.007 cm /Vs; μ =0.023 cm /Vs).
制备了四种取代并四苯，并通过紫外-可见光谱、电子顺磁共振光谱和X射线晶体学对其进行了表征。这些化合物是迄今为止最稳定且可溶的并四苯，这归因于六个经过策略性放置的三异丙基甲硅烷基（TIPS）-乙炔基。它们在固态下可稳定存在数周。在稀溶液中，它们的半衰期为5 - 9小时。对两种并四苯的晶体结构分析证实了其结构。一种并四苯衍生物在溶液处理的晶体管中进行了测试，表现出双极性电荷传输（μ = 0.007 cm²/Vs；μ = 0.023 cm²/Vs）。
