发现伯胺与In 37P20（O2CR）（51）的反应从In 37P20（O2CR）（51）中除去In（O2CR）（3）亚基。这种Z型配体的损失与结构重排相一致，以减轻核心应变和钝化磷原子。这一结果巩固了伯胺促进和阻碍InP纳米晶体的前体转化率的相互冲突的主张。
The reaction of primary amines with In37P20(O2CR)(51) is found to remove In(O2CR)(3) subunits from In37P20(O2CR)(51). This loss of Z-type ligands coincides with structural rearrangement to alleviate core strain and passivate phosphorus atoms. This result consolidates conflicting claims that primary amines both promote and retard precursor conversion rates for InP nanocrystals.
