合成了一系列低聚物（Me3Si）3GeGeCl3、（C6F5）3GeGePh3、（C6F5）3GeGe(p-Tol)3和（C6F5）2Ge[Ge(p-Tol)3]2，它们在相邻的锗原子上含有不同电子性质的取代基。根据x射线衍射研究、紫外/可见光谱学和量子化学计算，这些“供体-受体”寡聚物的电子跃迁能量低于其他类似化合物。
A series of oligogermanes, (Me3Si)3GeGeCl3, (C6F5)3GeGePh3, (C6F5)3GeGe(p-Tol)3, and (C6F5)2Ge[Ge(p-Tol)3]2, containing substituents with different electronic properties at neighboring germanium atoms were synthesized. According to X-ray diffraction studies, UV/visible spectroscopy, and quantum chemical calculations, these “donor–acceptor” oligogermanes are characterized by energies of electronic transitions lower than those for other similar compounds.
