The first example of a directed and regioselective arylation of polycyclic aromatic hydrocarbons (PAHs) by using a PO directing group is reported herein. The protocol uses a cheap copper catalyst, and results in a breakthrough meta-selective C–H functionalization of arylphosphine oxide compounds. Substrates with potential fluorescence properties, for example, pyrene and fluoranthene, were successfully
