Used in organic electronics due to its strong electron-donating properties and stability. Commonly applied in organic light-emitting diodes (OLEDs) as an emissive or charge-transport layer. Also investigated in organic photovoltaics (OPVs) for its ability to enhance light absorption and charge separation. Shows potential in fluorescent sensors and bioimaging because of its rigid, planar structure and tunable emission properties. Studied for use in pharmaceuticals due to its structural similarity to bioactive indole alkaloids, with research exploring antitumor and kinase-inhibiting activities.
