Stereospecific synthesis of chiral P-containing polyaromatics based on 7-membered P-rings

We present the stereospecific synthesis of helicenoid-based phosphepines (7-membered P-rings) as well as chiral P-containing polycyclic aromatic hydrocarbons. In these systems, an axial to central chirality transfer takes place from the BINAP moiety to the P-atom. The impact of the molecular design on the structure, the (chir)optical (including circularly polarized luminescence) and redox properties are investigated.

Automated summary

The stereospecific synthesis of helicenoid-based phosphepines and chiral P-containing polycyclic aromatic hydrocarbons is presented, with investigation into the impact of molecular design on structure, (chir)optical properties (including circularly polarized luminescence), and redox properties. An axial to central chirality transfer from the BINAP moiety to the P-atom is observed in these systems.
