We present a simple, easily scalable route to monodisperse copper sulfide nanocrystals by the hot injection of a series of novel copper(I) xanthate single-source precursors [(PPh)Cu(SCOR)] (R = isobutyl, 2-methoxyethyl, 2-ethoxyethyl, 1-methoxy-2-propyl, 3-methoxy-1-butyl, and 3-methoxy-3-methyl-1-butyl), whose crystal structures are also reported. We show that the width of the obtained rods is dependent on the length of the xanthate chain, which we rationalize through a computational study, where we show that there is a relationship between the ground-state energy of the precursor and the copper sulfide rod width.
我们通过热注入一系列新型的黄原酸铜（I）单源前驱体[（PPh）Cu（SCOR）]（R =异丁基、2-甲氧基乙基、2-乙氧基乙基、1-甲氧基-2-丙基、3-甲氧基-1-丁基和3-甲氧基-3-甲基-1-丁基），展示了一条制备单分散硫化铜纳米晶体的简单且易于扩展的途径，其晶体结构也有报道。我们表明，所得棒的宽度取决于黄原酸酯链的长度，我们通过计算研究对此进行了合理化解释，在该研究中我们表明前驱体的基态能量与硫化铜棒的宽度之间存在关系。
