Development of convenient synthesis of multi-substituted conjugated aromatic compounds by means of carbon-hydrogen and carbon-oxygen bonds cleavage

在这项研究中，我们通过Ru催化的芳香酮(包括苯乙酮和吩酮)中的碳氢键的区域选择性功能化，开发了方便地合成各种并苯衍生物的新条目，如并五烯、蒽、苦烯和二苯并茂。我们的烯烃合成方法可应用于芳香酮与芳基硼酸盐和/或烯烃的各种组合。测试了所合成的苯并苯的有机场效应晶体管(OFET)特性。由其中一些产品制成的OFET具有中等的空穴迁移率。

In this study, we developed new entries of convenient syntheses of various acene derivatives such as pentacenes, anthracenes, picenes, and dibenzoanthracenes by means of ruthenium-catalyzed regioselective functionalization of carbon-hydrogen bonds in aromatic ketones including acetophenones and acenequinones. Our synthetic procedures of acenes can be applied to a variety of combination of aromatic ketones with arylboronates and/or alkenes. The organic field effect transistor(OFET) properties of the synthesized acenes were measured. The OFET fabricated from some of the products gave moderate hole mobility.
