A new class of symmetric pi-conjugated donor-acceptor-donor (D-A-D) materials, with aryl- or heteroaryl[a]annulated carbazole (AHA[a]C) moieties as the donors and with 2,1,3-benzothiadiazole (BT) as an acceptor, has been synthesized via NaAuCl4-catalyzed double cascade cyclization of arenyl tetraynes in ethanol in good to high yields. Photophysical and electrochemical properties of the new D-A-D materials were investigated. (C) 2011 Elsevier Ltd. All rights reserved.
