Significant efforts have been devoted to developing new dopant-free holetransportingmaterials (HTMs) for perovskitesolarcells (PVSCs). Fluoranthene is one typical cyclopentene-fused polycyclic aromatic hydrocarbon with a rigid planarized structure, and thus could be an ideal building block to construct dopant-free HTMs, which have not been reported yet. Here, we report a new and simple synthetic
