项目摘要

The rapid structure elucidation of small-molecule-based crystalline material systems is an essential basis for the continuing competitive research at the Heinrich-Heine-University (HHU) of Düsseldorf in the field of materials, functional agents, catalysis, sensors and others. The availability of a modern area-detector single-crystal X-ray diffractometer with a micro-source exchange unit, which will only be used in research, is fundamental for the research projects at the HHU.In subprojects of the newly established Research Training Group 2482 (Modulation of Intersystem Crossing - ModISC) at the HHU, the structure determination of compounds investigated there is important. This structure determination can be carried out in the crystalline solid with the single-crystal diffractometer.The proposed diffractometer allows the determination of light atomic structures with very small crystals with dimensions well below 0.1 x 0.1 x 0.1 mm3, requires no cooling of the X-ray source and no high voltage power supply, so that compared to conventional devices significantly lower energy consumption and trouble-free continuous operation is guaranteed. Of the two existing diffractometers at the Düsseldorf structural chemistry institute, the single-crystal diffractometer obtained in 2012 is soon in need of replacement due to aging and due to the unfortunately already missing support (announced by the company Bruker).

小分子晶体材料系统的快速结构解析是杜塞尔多夫海因里希-海涅大学（HHU）在材料、功能剂、催化、传感器等领域持续开展竞争性研究的重要基础。现代化的面积探测器单晶X射线衍射仪的可用性与微源交换单元，这将只用于研究，是在HHU的研究项目的基础。在HHU新成立的研究培训组2482（调制系统间交叉- ModISC）的子项目，有研究的化合物的结构测定是重要的。这种结构测定可以用单晶衍射仪在结晶固体中进行。所提出的衍射仪允许用尺寸远低于0.1 × 0.1 × 0.1 mm 3的非常小的晶体测定轻原子结构，不需要冷却X射线源，也不需要高压电源，从而与传统设备相比，显著降低了能耗，并且保证了无故障的连续操作。在杜塞尔多夫结构化学研究所现有的两台衍射仪中，2012年获得的单晶衍射仪由于老化和不幸的是已经失去了支持（由布鲁克公司宣布），很快就需要更换。
