Rational Synthesis and Properties Evaluation of Oligoacene Derivatives

并苯是由线性稠合的苯环组成的典型芳烃，并且从实用观点来看作为功能有机材料是当代感兴趣的。在酮部分引入取代基后再还原低聚并苯醌是合成低聚并苯的合理路线之一。我们已经成功地合成了最大的低聚苯醌，九苯醌（9个苯环），并在其转化为醌亚胺与苯胺。亚胺的还原得到的紫外-可见吸收光谱可达1100 nm。我们还成功地合成了一种直接连接的并五苯二聚体。我们正试图在此基础上制造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.
