设计并合成了具有平面七元环的空气和湿气稳定的二苯并[b,f]加仑。通过 X 射线单晶分析，评估了镓原子配位数对具有一系列合成配合物的七元环平面性的影响。因此，结果表明，与其他具有四或五配位镓原子的二苯并没食子素相比，涉及三配位镓原子的二苯并没食子素七元环呈现出最高的平面度。此外，根据理论计算，有人提出配合物中镓原子的电子态对LUMOs+1的能级有贡献。
Air- and moisture-stable dibenzo[b,f]gallepins with planar seven-membered rings have been designed and synthesized. From X-ray single-crystal analyses, the effects of the coordination numbers were evaluated at the gallium atom on the planarity of the seven-membered rings with a series of the synthesized complexes. Accordingly, it was shown that the seven-membered ring of dibenzogallepin involving a three-coordinated gallium atom presented the highest planarity compared to other dibenzogallepins with four- or five-coordinated gallium atoms. In addition, from theoretical calculations, it was proposed that the electronic states of the gallium atom in the complexes contributed to the energy levels of LUMOs+1.
