A fused polycyclic compound containing phenothiazine and diazapyrene skeletons with weak D-A interactions.

A small fused polycyclic molecule containing a phenothiazine and diazapyrene skeleton as the donor and acceptor, respectively, has a redox potential similar to those of the corresponding donor and acceptor molecules, indicating that the inherent electronic properties of the donor and acceptor were retained due to weak orbital interactions.
