Step-efficient access to new starburst hole-transport materials with carbazole end-groups for perovskite solar cells via direct C–H/C–Br coupling reactions

Author affiliations

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%.
