Abstract: The present invention relates to a novel compound for improving the photostability of an optoelectronic device, and more particularly, to a novel phenanthroline-based compound, a preparation method thereof, and an optoelectronic device including the same as a passivation layer. According to the present invention, the novel phenanthroline-based compound of Formula 1 is a novel compound in which an amine group side chain is introduced into the parent nucleus of phenanthroline, and is capable of being used in a solution process due to excellent solubility in a polar solvent, and simple introduction on an n-type semiconductor organic layer (e.g., an organic photoactive layer or an electron transport layer) as a passivation layer may bring about not only an increase in stability, but also an additional increase in efficiency such as an increase in open-circuit voltage or photocurrent.
