Aurophilicity derived Functional Materials for Optoelectronics and Sub-Nano Physics

受新型混合价金化合物二（环己腈）金(I)四氯金酸酯（III）的启发，该项目重点研究(1)混合价金（I/III）和(2)金(I)化合物的合成，这两种化合物都是由于亲金吸引力而在交替的单离子和单阴离子金络合物链中结晶的，并确定它们的物理和光谱性质。从以前的研究中获得的具有无支撑亲金接触的大结构基础以及对其中的二级键的评估，使中性和阴离子配体对的设计成为可能，从而导致链状组装，从而合成定制的超分子金化合物。本项目的研究成果将有助于揭示金(I)和金（I/III）配合物的结构-发光关系。发光性质与手性的关联使新型手性传感和光电子器件的发展成为可能。该研究的另一个主要目标是在中孔碳和金属有机框架的有序腔内沉积亚纳米原子金线或原子金线的三维网络。宽度为1-2个原子的金(0)纳米线的实现仍然局限于基于AFM和stm的原子操纵技术。这样的原子结构对基本测量有很高的兴趣，例如量子电导，量子霍尔效应和原子尺度上的磁相互作用。

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.
