An interesting physical phenomenon, electroluminescence, that was originally observed with a hydrocarbon molecule has recently been developed into highly efficient organic light‐emitting devices. These modern devices have evolved through the development of multi‐element molecular materials for specific roles, and hydrocarbon devices have been left unexplored. In this study, we report an efficient organic light‐emitting device composed solely of hydrocarbon materials. The electroluminescence was achieved in the blue region by efficient fluorescence and charge recombination within a simple single‐layer architecture of macrocyclic aromatic hydrocarbons. This study may stimulate further studies on hydrocarbons to uncover their full potential as electronic materials.
