项目摘要
Chemical scientists have been inspired by natural product synthesis to develop highly sophisticated methodologies for organic transformations. Surprisingly, such tendency to develop methodologies for the efficient synthesis of organic materials can only be sparingly observed. However, the development of efficient methodologies for the synthesis of organic materials is of utmost importance. This lack of such synthetic methodology is addressed in the presented project by the efficient synthesis of sulfur-containing heteroacenes by modern transition metal catalysis.Sulfur-based anellated heteroacenes are semi-conductors, which find application in organic field-effect-trasistors (OFET). The access to such structures is often limited by the use of highly toxic and/or moisture- and oxygen-sensitive sulfur reagents. The presented project warrants for the straightforward approach to diversely substituted polyanellated sulfur- and sulfur/nitrogen-containing heteroacenes. This is achieved by a C-S cross coupling/cyclization domino reaction using thiourea as easy and safe to handle sulfur surrogate. Complementary to this strategy is the intramolecular cyclization of diarylthioethers and diarylamines by C-H activation. The intramolecular C-H activation/C-C coupling of bis(thiopene)thioethers or bis(thiophene)amines provides access to bisthienothiophenes and bisthienopyrroles. The modular synthesis of the cyclization precursors warrants for high diversity, thus allowing the modulation of the electronic properties of the systems.Novel heteroacenes will be evaluated in their capabilities to function as semi-conductors in OFET devices.
化学科学家受到天然产物合成的启发,开发了高度复杂的有机转化方法。令人惊讶的是,这种开发有效合成有机材料的方法的趋势只能很少地观察到。然而,开发用于合成有机材料的有效方法是至关重要的。本课题通过现代过渡金属催化剂高效合成含硫杂并苯来解决这一问题。硫基稠合杂并苯是一种半导体材料,在有机场效应晶体管(OFET)中有着广泛的应用。对这种结构的访问通常受到使用高毒性和/或对湿气和氧气敏感的硫试剂的限制。所提出的项目保证了直接的方法,以双取代的聚芳环化的含硫和硫/氮的杂并苯。这是通过使用硫脲的C-S交叉偶联/环化多米诺反应来实现的,因为硫脲是容易且安全地处理硫替代物。与此策略互补的是通过C-H活化的二芳基硫醚和二芳基胺的分子内环化。双(噻吩)硫醚或双(噻吩)胺的分子内C-H活化/C-C偶联提供了获得双噻吩并噻吩和双噻吩并吡咯的途径。环化前体的模块化合成保证了高度的多样性,从而允许调制的电子性质的systems.Novel杂并苯将在它们的能力进行评估,作为半导体在OFET器件。
