An efficientsynthesis of 6,7-disubstituted naphthoquinones and 2,3,6,7-tetrasubstituted anthraquinones were developed using the reaction of thiophene dioxides and benzoquinone and naphthoquinone derivatives, respectively.
Single crystal analysis of Q-BBT and S-BBT revealed profoundly distinct packing modes, which must be ascribed to the different molecular shapes. Experimental and theoretical studies indicated that both compounds give rise to electron-accepting materials. This work thus also contributes to the diversity of electron acceptors based on bis-benzothiadiazole moieties and highlights the important role of molecular
