The storage of solar energy in form of chemical energy in metastable isomers and its controlled release are the central aspects of the MOST technology. Within this project 1,2-dihydro-1,2-azaborines, the boron-nitrogen analogues of benzene (BNB), and their metastable Dewar isomers (BND) are investigated as harvesting and storage forms of solar energy. These compounds combine high energy content and long lifetime, but the overlap with the solar spectrum requires additional optimization. The major goal of the project is gaining understanding of the fundamental properties of the BNB/BND pair depending on parameters such as substituents, functional groups, and solvent. Based on this knowledge, we aim for developing BNB/BND systems with high storage energy densities, adjustable storage times, and absorption of sunlight. Within the project we will develop synthetic strategies for the efficient access of central synthetic intermediates in larger scale using flow chemistry techniques (work package 1). These central intermediates will be transferred into the target molecules in the other work packages, also by development of catalytic methods for functionalization in cooperation within FOR MOST. The fundamental understanding of the structure-property relationship governing the photochemically induced energy storage and the subsequent energy release will be developed in work package 2. The knowledge gained will guide us towards novel materials with high energy storage density, adjustable lifetime of the storage state (work package 3), and optimized match with the solar spectrum. Within FOR MOST the close intertwining of the project with partner projects will substantially contribute towards the better understanding of a novel molecular energy storage system and allow development of materials for future technology platforms.

在亚稳态异构体中以化学能的形式存储太阳能，其受控释放是最多技术的中心方面。在该项目中，将苯（BNB）的硼氮类似物（BNB）及其亚稳态露异构体（BND）作为收获和储存形式的太阳能研究。这些化合物结合了高能量含量和长寿命，但是与太阳光谱的重叠需要额外的优化。该项目的主要目的是了解BNB/BND对的基本特性，具体取决于诸如取代基，官能团和溶剂等参数。基于这些知识，我们旨在开发具有高储能密度，可调节存储时间和吸收阳光的BNB/BND系统。在项目中，我们将开发合成策略，以使用流动化学技术（工作包1）进行大规模的中央合成中间体有效访问。这些中心中间体将通过开发大多数人的合作功能化催化方法来转移到其他工作包中的目标分子中。对统治光化学诱导的能量存储和随后的能量释放的结构培训关系的基本理解将在工作包2中发展。获得的知识将指导我们朝着具有高能量存储密度的新型材料，可调节的存储状态（工作包3）的可调节寿命（工作包3），并且优化与Solar Spectrum匹配。在大多数人中，该项目与合作伙伴项目的紧密相互交织将有助于更好地理解新型分子储能系统，并允许为未来的技术平台开发材料。
