2D π-conjugated systems incorporated with heteroatoms can suffer from stability issues and aggregation-induced quenching effects. Here, the authors develop a methodology for the synthesis of cluster-ring-fused 3D aromatic heterocycles, which could find use in functional materials, via the palladium-catalyzed B–H activation of boron clusters.
