Discovering novel families of molecular polyhedra through graph theory has attracted increasing interests. Nevertheless, the design principles of molecular polyhedra based on graph theory remain elusive, especially for those containing five-node units. Herein, we construct a series of chiral truncated face-rotating polyhedra (T-FRP) from pentagonal pentaphenylpyrrole (PPP) derivatives and chiral diamines. The graph theory is used to elucidate the geometry of these novel T-FRP, which represent a new family of molecular polyhedra. The phenyl flipping of PPP faces in these T-FRP is significantly restricted, thus making T-FRP chiral and strongly emissive in solution. In addition, T-FRP also generate circularly polarized luminescence. This study provides new insights into the rational design of novel molecular polyhedra through graph theory.

五边形五苯基吡咯通过图论构造截断面旋转多面体

通过图论发现分子多面体的新家族引起了越来越多的兴趣。尽管如此，基于图论的分子多面体的设计原则仍然难以捉摸，尤其是对于那些包含五节点单元的多面体。在此，我们从五边形五苯基吡咯 (PPP) 衍生物和手性二胺构建了一系列手性截断面旋转多面体 (T-FRP)。图论用于阐明这些新型 T-FRP 的几何形状，它们代表了一个新的分子多面体家族。这些 T-FRP 中 PPP 面的苯基翻转受到显着限制，从而使 T-FRP 在溶液中具有手性和强发射性。此外，T-FRP 还产生圆偏振光。这项研究通过图论为新型分子多面体的合理设计提供了新的见解。
