Luminescence spectrometer with TCSPC-/MCS-module, integrating sphere for quantum yield determination, and cryostat

安德烈亚斯·斯特芬教授的团队致力于铜、银、锌等高丰度元素的D10过渡金属配合物的合成和光物理研究，以及它们作为传感器和光催化剂在发光器件中的应用。多特蒙德理工大学斯特芬教授的任命预计将加强功能材料领域的活动。为了实现拟议的工作和项目，下面将简要总结一下，购买发光光谱仪是强制性的，多特蒙德大学强烈支持这一应用。许多感兴趣的光活性金属络合物(见主要提案)显示，除了有效的三重态布居外，还有热激活延迟荧光，通过这种延迟荧光可以实现有益的短寿命和高发光效率。同时，我们认识到多金属络合物可以从多个激发态平行发射，这导致了分子白光发光体和刺激响应材料的发展。在另一个项目中，通过对敏化单元的激发态性质的详细分析，开发了基于能量转移的用于硼化和氢胺化反应的高效光催化剂。为了获得控制并允许针对激发态的寿命、能量和效率进行目标设计，阐明其发射特性和机理是至关重要的。只有这样才能建立结构与性质的关系，随后才能开发出应用于应用的超快发射器、高效光催化剂和传感器。为了彻底了解和完整的光物理特性(发射波长、激发波长、寿命、量子产额、低温行为)，绝对需要一台发光光谱仪。购买这台主要仪器的附加值是由于计划与多特蒙德大学的Guido Clear博士和Carsten Strohmann教授小组进行的具体合作。科林特教授的团队发表了他们在手性发光铂配合物以及光活性超分子笼状结构领域的首次尝试，在未来，他们将与斯特芬教授的团队一起研究光开关和响应结构。通过购买发光光谱仪，Strohmann教授的团队有机会在现场研究发光卤化铜簇合物和配位聚合物，这样即使是高灵敏度的化合物也可以测量其光物理。

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.
