Inspired from the novel mixed-valent gold compound bis(cyclohexylnitrile)gold(I) tetrachloridoaurate(III) this project focusses on the synthesis (1) of mixed-valent gold(I/III) and (2) of gold(I) compounds, both crystallizing in chains of alternating monocationic and monoanionic gold complexes owing to aurophilic attraction, and on the determination of their physical and spectroscopic properties. The large fundament of structures with unsupported aurophilic contacts from former research and the evaluation of the secondary bonding therein enable the design of pairs of neutral and anionic ligands leading to chain-like assembly and, thus, the synthesis of tailored supramolecular gold compounds. The insights from this project will shed light on the structure-luminescence relationship of gold chains consistent of alternating cationic and anionic gold(I) and gold(I/III) complexes. The association of luminescent properties with chirality allows the development of novel chiral sensing and optoelectronic devices. Another main objective of this fellowship is the deposition of sub-nano wires of atomic gold or three-dimensional networks of atomic gold wires within the ordered cavities of mesoporous carbon and metal-organic frameworks. The realization of gold(0) nanowires with a width of 1-2 atoms is still limited to AFM- and STM-based atom manipulation techniques. Such atomic structures are of high interest for fundamental measurements, e.g. quantum conductance, the quantum Hall effect and magnetic interaction on an atomic scale.

受新型混合价金化合物双（环己基腈）金（I）四氯金酸盐（III）的启发，该项目专注于（1）混合价金（I/III）和（2）金（I）化合物的合成，由于亲金吸引力，这两种化合物都以交替的单阳离子和单阴离子金络合物的链结晶，并测定其物理和光谱性质。从以前的研究和评估的二级键合的结构与未支持的亲金接触的大基础，使设计的中性和阴离子配体对导致链状组装，因此，定制的超分子金化合物的合成。从这个项目的见解将阐明交替阳离子和阴离子金（I）和金（I/III）配合物的金链的结构-发光关系。发光特性与手性的关联允许开发新的手性传感和光电器件。该奖学金的另一个主要目标是在介孔碳和金属有机框架的有序空腔内沉积原子金的亚纳米线或原子金线的三维网络。金（0）纳米线的宽度为1-2个原子的实现仍然限于AFM和STM为基础的原子操纵技术。这样的原子结构对于基本测量，例如量子电导、量子霍尔效应和原子尺度上的磁相互作用具有高度兴趣。
