features a polycyclic aromatic hydrocarbon, 9,19-dihydrobenzo[1',10']phenanthro[3',4':4,5]thieno[3,2-b]benzo[1,10]phenanthro[3,4-d]thiophene, coupled with a diarylamine electron donor and 4-(7-ethynylbenzo[c][1,2,5]thiadiazol-4-yl)benzoic acid acceptor. Dye R6 displays a brilliant sapphire color in a sensitized TiO2 mesoporous film with a Co(II/III) tris(bipyridyl)-based redox electrolyte. The R6 based dye-sensitized
active: A silica‐supported “compact” phosphane, Silica‐SMAP, can be used in the Pd‐catalyzedborylation of aryl chlorides or bromides with bis(pinacolato)diboron (see scheme). The Silica‐SMAP/Pd system significantly expands the substrate scope of the borylation toward sterically and electronically challenging arylhalides.
