The present invention provides: a layered structure having a substrate and a hole injection and/or hole transport layer comprising an aromatic compound having, on a side chain, at least one type of group having a cationic center;
an electronic device having the layered structure;
an aromatic compound having, on a hydrocarbon side chain, at least one type of group having a cationic center;
an aromatic compound having a leaving group on a hydrocarbon side chain;
and a method for manufacturing the aromatic compound having, on a hydrocarbon side chain, at least one type of group having a cationic center, the method comprising reacting the aromatic compound having a leaving group on a hydrocarbon side chain with a specific nitrogen compound, phosphorus compound, sulfur compound, or a combination of two or more of these compounds, thereby converting the aromatic compound into an onium salt thereof. When used as an electronic device material, and particularly as a hole transport and/or hole injection material, the aromatic compound can achieve a higher current density at a given voltage.
