| Abstract: | A new class of symmetric π-conjugated donor–acceptor–donor (D–A–D) materials, with aryl- or heteroaryla]annulated carbazole (AHAa]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. |
