“…4,7-dibromo- [1,2,5]thiadiazolo [3,4-c]pyridine (1) [11], (4-(diphenylamino)phenyl)boronic acid (3) [12], (9-hexyl-9H-carbazol-3-yl)boronic acid (4) [13], tert-butyl 2-cyano-3-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)acrylate (5) [14] and tert-butyl 2-cyano-3-(5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)thiophen-2-yl)acrylate (6) [14] were prepared according to the published methods and characterized by NMR spectra. The synthetic routes for these building blocks are shown in Scheme 2.…”
