The group of Prof. Dr. Andreas Steffen has focussed on the synthesis and photophysical investigation of d10 transition metal complexes of highly abundant elements such as copper, silver and zinc, and their application in light-emitting devices, as sensors and photocatalysts. The appointment of Prof. Steffen at the TU Dortmund is expected to strengthen the activities in the area of functional materials. In order to realize the proposed work and projects, which will be briefly summarized in the following, the purchase of a luminescence spectrometer is mandatory and the TU Dortmund strongly supports this application.Many of the photoactive metal complexes of interest (see main proposal) show, apart from efficient triplet state population, thermally activated delayed fluorescence, by which beneficial fast lifetimes and high luminescence efficiencies can be realized. Also, we realized that multimetallic complexes can emit from several excited states in parallel, which led to the development of molecular white light emitters and stimulus-responsive materials. In another project, highly efficient photocatalysts for borylation and hydroamination reactions based on energy transfer have been developed by a detailed analysis of the excited state properties of the sensitizer units.In order to gain control and to allow for target-oriented design of the excited states with regard to lifetime, energy and efficiency, the elucidation of the emission properties and mechanisms is of utmost importance. Only then structure-property relationships can be formulated and subsequently ultrafast emitters, highly efficient photocatalysts and sensors can be developed for applications. For a thorough understanding and full photophysical characterisation (emission wavelengths, excitation wavelengths, lifetimes, quantum yields, low temperature behaviour) a luminescence spectrometer is absolutely mandatory.An added value results from the purchase of this major instrument due to planned specific collaborations with the groups of Prof. Dr. Guido Clever and Prof. Dr. Carsten Strohmann at the TU Dortmund. The group of Prof. Clever published their first forays in to the field of chiral luminescent platinum complexes as well as of photoactive supramolecular cage structures, and in the future they will investigate photoswitchable and –responsive structures together with the group of Prof. Steffen. With the purchase of the luminescence spectrometer, the group of Prof. Strohmann has the opportunity to study luminescent copper halide cluster compounds and coordination polymers on-site, so that even highly sensitive compounds can be measured with regard to their photophysics.

Andreas Steffen教授的团队专注于高含量元素（如铜、银和锌）的d10过渡金属配合物的合成和光物理研究，以及它们在发光器件中的应用，如传感器和光催化剂。Steffen教授在多特蒙德工业大学的任命预计将加强功能材料领域的活动。为了实现提议的工作和项目，下面将简要总结，必须购买一台发光光谱仪，多特蒙德工业大学强烈支持这一申请。许多感兴趣的光活性金属配合物（见主要建议）显示，除了有效的三重态居群外，热激活的延迟荧光可以实现有益的快速寿命和高发光效率。此外，我们意识到多金属配合物可以从多个激发态并行发射，这导致了分子白光发射器和刺激响应材料的发展。在另一个项目中，通过详细分析敏化剂单元的激发态性质，开发了基于能量转移的高效硼化和氢胺化反应光催化剂。为了获得控制，并允许目标导向的激发态的设计，关于寿命，能量和效率，发射特性和机制的阐明是至关重要的。只有这样，结构-性能关系才能形成，随后超快发射器，高效光催化剂和传感器才能开发应用。为了彻底了解和充分的光物理特性（发射波长，激发波长，寿命，量子产率，低温行为），发光光谱仪是绝对必要的。由于计划与多特蒙德工业大学的Guido Clever博士教授和Carsten Strohmann博士教授小组进行具体合作，因此购买这一主要仪器产生了附加价值。Clever教授小组发表了他们在手性发光铂配合物和光活性超分子笼结构领域的首次尝试，未来他们将与Steffen教授小组一起研究光开关和响应结构。由于购买了发光光谱仪，Strohmann教授的团队有机会在现场研究发光的卤化铜簇化合物和配位聚合物，因此即使是高度敏感的化合物也可以测量它们的光物理特性。
