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

Abstract

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...

Perylene with peripherally fused pyrrole and pyridine: columnar packing, anti-Kasha dual emission and reactive oxygen species generation

“…2 Thus, compact D-A-type fused-ring systems with flat structures, though limited, are essential for obtaining some desired functions. 3 Fusing polycyclic aromatic hydrocarbons (PAHs) with Nheterocycles, especially doping N heteroatoms marginally at the perimeters are always related to intriguing properties. 4 Firstly, a pyrrole type heterocycle is electron rich with a five-membered ring, which will induce acid response, high strain and supramolecular interaction/assembly with electron acceptors.…”
