Structural isomerism in ligated gold clusters is revealed using electrospray ionization ion mobility spectrometry mass spectrometry. Phosphine ligated Au clusters are shown to adopt more extended type structures with increasing exchange of methyldiphenylphosphine (MePPh) for triphenylphosphine (PPh). These ligand-dependant structure-property relationships are critical to theoretical modeling of clusters as well as their applications in catalysis and photovoltaics.
利用电喷雾电离离子淌度光谱质谱法揭示了连接金团簇中的结构异构现象。研究表明，随着甲基二苯基膦（MePPh）取代三苯基膦（PPh）的比例增加，膦连接的金团簇会采用更伸展的结构类型。这些依赖配体的结构-性质关系对于团簇的理论建模及其在催化和光伏领域的应用至关重要。
