The first representatives of the tetranuclear gold(i) complexes of P,N-containing cyclophanes with two 1,5-diaza-3,7-diphosphacyclooctane rings incorporated into the macrocyclic core have been obtained. The complexation leads to a change in ligand conformations so that the diazadiphosphacyclooctane fragments of the complexes adopt twist-chair conformations, and two of the four gold(i) ions are located over and under the partially collapsed macrocyclic cavity. The complexes demonstrate moderate solid-state green emission.
首例含两个 1,5-二氮杂-3,7-二磷杂环辛烷环的 P,N-环芳烃四核金(i)配合物的代表物已经被获得。该配合物导致配体构象发生变化，使得配合物的二氮杂二磷杂环辛烷片段采用扭曲椅构象，四个金(i)离子中的两个位于部分塌陷的大环腔的上方和下方。这些配合物表现出中等强度的固态绿色发光。
