چکیده
Nitrogen-bridged donor-acceptor multifused dithienopyrrolobenzothiadiazole (DTPBT) and dibenzothiadiazolopyrrolothiophene (DBTPT) were successfully synthesized by intramolecular Cadogan annulation. The electron-deficient benzothiadiazole unit in DTPBT can be converted to benzoselenadiazole and quinoxaline moieties through reduction/cyclization to generate dithienopyrrolobenzoselenadiazole (DTPBSe) and dithienopyrroloquinoxaline (DTPQX), respectively. The nitrogen atoms function as the bridges for covalent planarization to induce intermolecular interaction and intramolecular charge transfer.

A versatile synthesis of diverse 3,4-fused cinnolines via the base-catalysed condensation of 2-amino-2'-nitrobiaryls.
Benzo[c]cinnolines, thieno[3,2-c]cinnolines, pyrido[3,2-c]cinnolines and the previously undescribed quinoxalino[6,7-c]cinnoline ring system are conveniently prepared by a short synthetic route comprised of Suzuki coupling, base-catalysed cyclisation and deoxygenation. The use of tandem borylation-Suzuki coupling further extends the scope of this process to include highly substituted benzo[c]cin...
