The title electron acceptors, TSDA (2) and BSDA (3), were prepared which crystallize isomorphously with the sulfur analogue, BTDA (1). The molecular interactions are enhanced in 2 and 3 compared with 1, which connect the molecules to form two-dimensionally expanded “sheet-like” networks and their infinite layers.
