设计并合成了一种面外各向异性π共轭分子三硫代磷杂环戊烯。将三个各向异性硫化膦部分插入苏曼烯骨架中诱导了具有大偶极矩（12.0 D）的累积各向异性，该偶极矩相对于π-骨架在垂直方向上对齐，并且是常规的面外各向异性分子的两倍多。在晶体中，分子排列形成柱状结构，其中π骨架的富电子侧和缺电子侧彼此面对。用X射线光电子能谱研究了含三个硫原子的富电子表面与Au（111）的相互作用。
A triphosphasumanene trisulfide was designed and synthesized as an out-of-plane anisotropic pi-conjugated molecule. Incorporating three anisotropic phosphine sulfide moieties into a sumanene skeleton induced a cumulative anisotropy with a large dipole moment (12.0 D), which is aligned in perpendicular direction with respect to the pi-framework and more than twice as large as those of conventional out of-plane anisotropic molecules. In the crystal, the molecules align to form columnar structures, in which electron-rich and electron-deficient sides of the pi-framework face each other. The interactions between the electron-rich surfaces, which contain three sulfur atoms, and Au(111) were examined by X-ray photoelectron spectroscopy.
