Donor–acceptor π-conjugated (D–π–A) organic molecules bearing both electron-donating and electron accepting moieties linked by a π-conjugated bridge are an important class of organic functional materials, which exhibit intramolecular charge transfer from the donor to the acceptor moiety. Numerous D–π–A structural organic molecules have been synthesised and used in solar cells, organic light emitting diodes, nonlinear optics and fluorescence sensors.

In this paper, the authors report the design and synthesis of four novel D–π–A structural 1-aryl-2-[4-(N,N- diphenyl)phenyl]-4,5-diphenyl-1H-imidazoles. Their synthesis, thermal stability, optical properties and electrochemical behaviour have also been investigated.
