Today’s technologies are capable of converting solar energy to electricity directly (photovoltaics) or indirectly (wind energy or hydropower) at a large scale and at a cost efficiency which is steadily improving. However, the availability of solar energy varies drastically in space and time. Therefore, energy storage is the primary challenge in our transition to a renewable energy system. Here, new molecular materials may pave the road to a phenomenal variety of new and surprising solutions. In the Research Unit FOR MOST, we propose to explore the potential of such a powerful molecular strategy: The conversion, storage and release of solar energy, all combined in just one single molecule so-called Molecular Solar Thermal (MOST) systems. The working principle is as follows: A switchable molecule absorbs light and is converted from a low-energy state to a metastable high-energy state. To release the stored energy, an external trigger (heat, catalyst, light, electric or magnetic field), is applied and the molecule returns to its low-energy state converting the chemical energy to heat. The concept possesses the big advantage that energy capture, storage and release can be accomplished in a very simple medium consisting of the photochromic molecules only. The key components in MOST systems are tailor-made photoswitches, which must be designed to fulfill specific criteria in the best possible way: • High energy storage density with a long half-life of the metastable high-energy state • Efficient photoconversion (high quantum efficiency, good match to the solar spectrum) • High reversibility and good stability (i.e. high selectivity of the conversion and back conversion reaction with minimal degradation) The design of MOST systems poses great challenges to synthetic chemistry. Hence, it is clear that a multidisciplinary approach is indispensable which combines the expertise (i) to develop new MOST switches (synthesis), (ii) to explore their functionality (spectroscopy), (iii) to model their properties (theory) and (iv) to test them in demonstrating devices. In the proposed Research Unit FOR MOST, we will bring together the required expertise to form a spear-heading research team in Germany, which along with leading international researchers, will push the emerging field of MOST to the next level. However, the knowledge obtained goes far beyond the MOST concept and will make valuable contributions in the general field of organic photochemistry.

当今的技术能够将太阳能直接转换为电动（光伏）或间接（风能或水力发电），并以稳步提高的成本效率进行转换。但是，太阳能在空间和时间上的可用性各种。因此，储能是我们过渡到可再生能源系统的主要挑战。在这里，新的分子材料可能会铺平道路，通向各种新的和令人惊讶的解决方案。在大多数研究单元中，我们建议探索这种强大的分子策略的潜力：太阳能的转换，存储和释放，所有这些都仅以一个单个分子所谓的分子太阳能热（大多数）组合在一起。工作原理如下：可切换分子吸收光，并从低能状态转化为亚稳态的高能状态。为了释放存储的能量，应用了外部触发器（热，催化剂，光，电场或磁场），并将分子返回其低能状态，将化学能转化为热量。该概念可以在一个非常简单的介质中仅由光致变色分子组成的非常简单的介质来实现能量捕获，存储和释放的最大优势。 The key components in MOST systems are tailor-made photoswitches, which must be designed to fulfill specific criteria in the best possible way: • High energy storage density with a long half-life of the metastable high-energy state • Efficient photoconversion (high quantum efficiency, good match to the solar spectrum) • High reversibility and good stability (i.e. high selectivity of the conversion and back conversion reaction with minimal degradation) The大多数系统的设计对合成化学面临着巨大的挑战。因此，很明显，多学科的方法是必不可少的，它结合了专业知识（i）开发新的大多数开关（综合），（ii）探索其功能（光谱），（iii），以建模其属性（理论）和（iv），以在演示设备中测试它们。在大多数人提出的研究部门中，我们将汇集所需的专业知识，以组成德国的长矛研究团队，该研究团队将与领先的国际研究人员一起，将新兴领域的最高领域推向新的水平。但是，获得的知识远远超出了最大的概念，并且将在有机光化学的一般领域做出宝贵的贡献。
