Provided are an organic light-emitting compound that is a diarylethene derivative represented by Formula 1, and an organic electroluminescent (EL) device using the organic light-emitting compound, and a method of manufacturing the organic EL device: where R<SUB>1, </SUB>Ar<SUB>1, </SUB>Ar<SUB>2, </SUB>Ar<SUB>3</SUB>, Ar<SUB>4</SUB>, Ar<SUB>5</SUB>, Ar<SUB>6, </SUB>k, l, m, and n are the same as defined in the specification. The organic light-emitting compound contains a cis-diarylethene group linked with an aliphatic ring, and thus crystallization of the organic light-emitting compound is unlikely to occur and the compound is highly soluble to organic solvents and easily provides liquid formulation with organic solvents. Thus, the organic light-emitting compound can easily be used in organic EL devices. An organic EL device manufactured using the compound can have a thermostable layer and thus has improved light-emitting properties in term of superior turn-on voltage, efficiency, color purity, etc.
