Rational Synthesis and Properties Evaluation of Oligoacene Derivatives

丙烯腈是典型的由线性融合苯环组成的芳香烃，从实用的角度来看，它是一种功能有机材料。低聚丙烯酸甲酯的合理合成途径之一是在酮部引入取代基后使低聚丙烯酸甲酯醌还原。我们已经成功合成了最大的低聚苊烯醌，非苊烯醌（9个苯环），并将其与苯胺转化为醌亚胺。亚胺的还原使紫外-可见吸收光谱达到1100nm。我们还成功地合成了一种直接连接的并五烯二聚体。我们正尝试在此基础上制造FET器件。

Acenes are typical aromatic hydrocarbons composed of linearly fused benzene rings and of contemporary interest from a practical standpoint as functional organic materials. One of the rational synthetic routes to the oligoacene is that the reduction of the oligoacene quinone after introduction of substituents at the ketone parts. We have already succeeded in synthesis of the largest oligoacenequinone, nonacenequinone (9 benzene rings), and in its transformation to the quinoneimine with anilines. Reduction of the imine gave the UV-vis absorption spectrum up to 1100 nm.We have also succeeded in synthesis of a directly linked pentacene dimer. We are trying to make FET devices based on it.
