A new 2,7,10,15-tetraethynyldibenzo[g,p]chrysene ligand () and two tetranuclear gold(I) derivatives containing PPh () and PMe () phosphines were synthesized and characterized by H and P NMR, IR spectroscopy, and high-resolution mass spectrometry. The compounds were studied in order to analyze the effect of the introduction of gold(I) on the supramolecular aggregation and photophysical properties. Absorption and emission spectra displayed broad bands due to the establishment of π π interactions as an indication of intermolecular contacts and the formation of aggregates. A decrease of the recorded quantum yield (QY) of the gold(I) derivatives was observed compared to the uncomplexed ligand. The introduction of the complexes into poly methyl methacrylate (PMMA) and Zeonex 480R matrixes was analyzed, and an increase of the measured QY of in Zeonex was observed. No phosphorescent emission was detected.
一种新的 2,7,10,15-四乙炔基二苯并[g,p]苝配体（）和两个含有 PPh（）和 PMe（）膦的四核金（I）衍生物被合成并通过 H 和 P NMR、IR 光谱和高分辨率质谱进行了表征。这些化合物被研究以分析金（I）的引入对超分子聚集和光物理性质的影响。吸收和发射光谱显示由于π-π相互作用的建立而出现宽带，这表明存在分子间接触和聚集体的形成。与未配位的配体相比，观察到金（I）衍生物的记录量子产率（QY）降低。分析了将配合物引入聚甲基 methacrylate（PMMA）和 Zeonex 480R 基质中的情况，并观察到在 Zeonex 中测量的 QY 增加。未检测到磷光发射。
