A silicon-based compound represented by Formula 1 below and an organic light-emitting device including the silicon-based compound are provided. According to one or more embodiments of the present invention, an organic light-emitting device includes: a substrate; a first electrode; a second electrode disposed opposite to the first electrode; and an organic layer disposed between the first electrode and the second electrode and including an emission layer, wherein the organic layer include at least one of the silicon compounds of Formula 1
Bromination of 4H-cyclopenta[def] phenanthren-1-amine, -2-amine, -3-amine, or -8-amine with bromine in chloroform took place at the 2-, 1-, 8-, or 9-position, respectively. The second bromine was introduced at the 8-, 3-, 2-, or 3-position. Similar regioselectivity was observed in the system of bromine in acetic acid–48% hydrobromic acid and of hydrobromic acid in dimethyl sulfoxide. The corresponding
