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.

以亚稳态异构体化学能形式存储太阳能及其受控释放是 MOST 技术的核心内容。在该项目中，研究了 1,2-二氢-1,2-氮杂硼烷、苯的硼氮类似物 (BNB) 及其亚稳态杜瓦异构体 (BND) 作为太阳能的收集和储存形式。这些化合物结合了高能量含量和长寿命，但与太阳光谱的重叠需要额外的优化。该项目的主要目标是了解 BNB/BND 对的基本特性，具体取决于取代基、官能团和溶剂等参数。基于这些知识，我们的目标是开发具有高存储能量密度、可调节存储时间和吸收阳光的 BNB/BND 系统。在该项目中，我们将制定合成策略，利用流动化学技术（工作包 1）大规模有效获取中心合成中间体。这些中心中间体将被转移到其他工作包中的目标分子中，同时也通过与 FOR MOST 合作开发功能化催化方法。对控制光化学诱导能量存储和随后能量释放的结构-性能关系的基本理解将在工作包 2 中得到发展。所获得的知识将指导我们开发具有高能量存储密度、可调节存储状态寿命的新型材料（工作包3），并与太阳光谱进行优化匹配。在 FOR MOST 中，该项目与合作伙伴项目的紧密结合将大大有助于更好地理解新型分子储能系统，并为未来技术平台开发材料。
