Abstract

New starburst small molecules bearing carbazole end-groups are step-economically synthesized in good isolated yields (70–84%) by sequential C–H activation/arylation reactions. Perovskite solar cells employing these molecules (YC05–08) as hole-transporting materials (HTMs) display a promising power conversion efficiency of up to 17.4%.
