The preparation of large rylenes often needs the use of solubilizing groups along the rylene backbone, and all the substituents of the terrylenes and quaterrylenes were introduced before creating the rylene skeleton. In this work, we successfully synthesized 2,5,10,13-tetrakis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)terrylene (<b>TB4</b>) by using an iridium-catalyzed direct borylation of C-H bonds in terrylene in 56% yield. The product is soluble in common organic solvents and could be puri ...[more]
