Chemistry of Free Boroles

硼环由一个不饱和的五元杂环和一个三配位硼原子组成，具有令人兴奋的光学和电子性质。虽然先前的研究表明，环取代基在小孔的性质中起着至关重要的作用，但由于分离的衍生物数量有限，它们的确切影响尚不清楚。因此，该项目旨在开发一种新的通用合成路线，以获得各种各样的小孔结构，从而允许系统地研究它们的结构-功能关系。新方法还提供了在主链中制备由功能硼酸基团组成的共轭聚合物的机会，这些聚合物将被研究以阐明其物理化学特性。我们的工作的另一个重点是在阴离子自由基形式的小孔，特别是这些自由基之间的相互作用在明确定义的分子系统。这些系统的研究证明了小孔作为高自旋材料的基础材料的潜力，也有助于理解共轭有机硼烷聚合物中存在的电荷输运现象，这对功能材料越来越重要。

Boroles display exciting optical and electronic properties derived from their antiaromatic structure, comprising an unsaturated five-membered heterocycle with a three-coordinate boron atom. While previous research has shown that the ring substituents play a crucial role in the properties of the boroles, their exact influence remains unclear, owing to the limited number of isolated derivatives. Thus, this project aims at developing a new general synthetic route to access a wide variety of borole architectures, thereby allowing a systematic investigation of their structure-function relationship. The new approach also offers the opportunity to prepare conjugated polymers composed of functional borole moieties within the main chain that will be studied to elucidate their physicochemical characteristics. Another focus of our work is on the anion radical forms of the boroles and in particular the interaction between these radicals in well-defined molecular systems. These systematic studies should demonstrate the potential of boroles as building blocks for high-spin materials and also aid in understanding the charge transport phenomena present in conjugated organoborane polymers, which are becoming increasingly important for functional materials.
