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

Andreas Steffen教授和博士的团队专注于铜、银和锌等高丰度元素的d10过渡金属配合物的合成和电子物理研究，以及它们在发光器件中作为传感器和光催化剂的应用。斯特芬教授在多特蒙德工业大学的任命预计将加强在功能材料领域的活动。为了实现所提出的工作和项目，这将在下面简要总结，购买发光光谱仪是强制性的，多特蒙德工业大学大力支持这一应用。（见主要建议）显示，除了有效的三重态人口，热激活延迟荧光，由此可以实现有益的快速寿命和高发光效率。同时，我们认识到多金属配合物可以从多个激发态并行发射，这导致了分子白色发光体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硼化和氢胺化反应的高效光催化剂。为了获得控制，并允许在寿命、能量和效率方面对激发态进行目标导向设计，阐明发光性质和机理至关重要。只有这样，才能制定结构-性能关系，随后才能开发出超快发射器，高效光催化剂和传感器。为了彻底了解和全面的物理特性（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TU多特蒙德的Guido Clever教授博士和Carsten Strohmann教授博士团队进行具体合作，购买这台主要仪器带来了附加值。Clever教授的研究小组首次涉足手性发光铂络合物以及光敏超分子笼状结构领域，未来他们将与Steffen教授的研究小组一起研究光开关和响应结构。通过购买发光光谱仪，Strohmann教授的团队有机会现场研究发光卤化铜簇合物和配位聚合物，因此即使是高灵敏度的化合物也可以测量其物理性质。

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.
