The synthesis of III-V quantum dots has been long known to be more challenging than the synthesis of other types of inorganic quantum dots. This is attributed to highly reactive group-V precursors. We synthesized molecules that are suitable for use as group-V precursors and characterized their reactivity using multiple complementary techniques. We show that the size distribution of indium arsenide
众所周知,III-V 族量子点的合成比其他类型的无机量子点的合成更具挑战性。这归因于高反应性的 V 族前体。我们合成了适合用作 V 族前体的分子,并使用多种互补技术表征了它们的反应性。我们表明,砷化铟量子点的尺寸分布确实随着前体反应性的降低而改善。

The reactions of Fe(CO)2(NO)2 or Co(CO)3(NO) with As(tBu)3, As(tBu)2(M-Me3), or As(tBu)(MMe3)2 (M Si, Ge, Sn) proceed with the elimination of one CO ligand and the formation of the corresponding carbonyl-dinitrosyl-arsine-iron or dicarbonyl-nitrosyl-arsine-cobalt complexes, respectively. The UV and IR spectra as well as the 1H, 13C, 29Si, 59Co and 119Sn NMR spectra of the new complexes are described
