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.

alternation relevant to the Mills−Nixoneffect. Most importantly, the efficient synthesis of 1s crystals of extraordinary quality allows us (for the first time) to make precise electron-density measurements of the “banana-type” distortion and the ellipticity (π-character) of the various aromatic C−C bondssufficient to identify the electronic origin of the classical Mills−Nixoneffect. The unique electron-donor
